Previous implementation had an issues:
- macros murmur1 assumes murmur_step takes rotation value
as a second argument
- but murmur_step second argument is "next block"
- this makes st_hash_uint and st_hash_end to not mix high bits of
hash value into lower bits
- this leads to pure hash behavior on doubles and mixing hashes using
st_hash_uint.
It didn't matter when bins amount were prime numbers, but it hurts
when bins are powers of two.
Mistake were created cause of attempt to co-exist Murmur1 and Murmur2
in a same code.
Change it to single hash-function implementation.
- block function is in a spirit of Murmur functions,
but handles inter-block dependency a bit better (imho).
- final block is read in bit more optimal way on CPU with unaligned word access,
- final block is mixed in simple way,
- finalizer is taken from MurmurHash3 (it makes most of magic :) )
(64bit finalizer is taken from
http://zimbry.blogspot.ru/2011/09/better-bit-mixing-improving-on.html)
Also remove ST_USE_FNV1: it lacks implementation of many functions,
and looks to be abandoned

rb_autoload_str may be safer by preventing premature GC. It
can also be more efficient by passing a pre-frozen string that
can be deduped using rb_fstring. Common autoload callers (e.g.
rubygems, rdoc) already use string literals as the file
argument.
There seems to be no reason to expose rb_autoload_str to the
public C API since autoload is not performance-critical.
Applications may declare autoloads in Ruby code or via
rb_funcall; so merely deprecate rb_autoload without exposing
rb_autoload_str to new users.

This is an implementation detail and should not be exposed to
C extension users. We may change this to id_table soon; and
id_table should not be exposed as a public API.
It is highly unlikely any existing C extensions require this;
so the risk of breakage is very low. Ideally, all of RObject
could be hidden.

struct method_table_wrapper was introduced to avoid duplicate marking
for method tables.
For example, `module M1; def foo; end; end` make one method table
(mtbl) contains a method `foo`. M1 (T_MODULE) points mtbl.
Classes C1 and C2 includes M1, then two T_ICLASS objects are created
and they points mtbl too. In this case, three objects (one T_MODULE
and two T_ICLASS objects) points same mtbl. On marking phase, these
three objects mark same mtbl. To avoid such duplication, struct
method_table_wrapper was introduced.
However, created two T_ICLASS objects have same or shorter lifetime
than M1 (T_MODULE) object. So that we only need to mark mtbl from M1,
not from T_ICLASS objects. This patch tries marking only from M1.
Note that one `Module#prepend` call creates two T_ICLASS objects.
One for refering to a prepending Module object, same as
`Module#include`. We don't nedd to care this T_ICLASS.
One for moving original mtbl from a prepending class. We need to
mark such mtbl from this T_ICLASS object. To mark the mtbl,
we need to use `RCLASS_ORIGIN(klass)` on marking from a prepended
class `klass`.

This ensures a consistent implementation between 32 and 64-bit
platforms, as vm_trace.c limits events to 32-bits. This can
also open up struct packing opportunities.

This keeps ci->flag and ci->aux.index consistent across 32-bit
and 64-bit platforms.
ci->flag: VM_CALL_* flags only use 9 bits, currently
ci->aux.index: 2 billion ivars per class should be enough for anybody
This saves around 50K allocations on "valgrind ruby -e exit" on x86-64
before:
total heap usage: 48,122 allocs, 19,253 frees, 8,099,197 bytes allocated
after:
total heap usage: 48,069 allocs, 19,214 frees, 8,047,266 bytes allocated
* vm_core.h (rb_call_info_t): ci->flag becomes 32-bit unsigned int
ci->index becomes a 32-bit signed int (from signed long).
Reorder for better packing on 64-bit, giving an 8 byte reduction
from 104 to 96 bytes for each ci.
* compile.c (new_callinfo, setup_args, iseq_compile_each,
iseq_build_from_ary_body): adjust for type changes
* vm_insnhelper.c (vm_getivar): ditto

Please refer this ticket for details.
This change also introduces the following changes.
* Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3).
Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in
RBasic::flags (2 bit). Age == 3 objects become old objects.
* WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap.
* LONG_LIVED bitmap to represent living objects while minor GCs
It specifies (1) Old objects and (2) remembered shady objects.
* Introduce rb_objspace_t::marked_objects which counts marked
objects in current marking phase. marking count is needed to
introduce incremental marking.
* rename mark related function and sweep related function to
gc_(marks|sweep)_(start|finish|step|rest|continue).
* rename rgengc_report() to gc_report().
* Add obj_info() function to get cstr of object details.
* Add MEASURE_LINE() macro to measure execution time of specific line.
* and many small fixes.
* include/ruby/ruby.h: add flag USE_RINCGC.
Now USE_RINCGC can be set only with USE_RGENGC.
* include/ruby/ruby.h: introduce FL_PROMOTED0 and add FL_PROMOTED1
to count object age.
* include/ruby/ruby.h: rewrite write barriers for incremental marking.
* debug.c: catch up flag name changes.
* internal.h: add rb_gc_writebarrier_remember() instead of
rb_gc_writebarrier_remember_promoted().
* array.c (ary_memcpy0): use rb_gc_writebarrier_remember().
* array.c (rb_ary_modify): ditto.
* hash.c (rb_hash_keys): ditto.
* hash.c (rb_hash_values): ditto.
* object.c (init_copy): use rb_copy_wb_protected_attribute() because
FL_WB_PROTECTED is moved from RBasic::flags.
* test/objspace/test_objspace.rb: catch up ObjectSpace.dump() changes.

* include/ruby/io.h (rb_io_buffer_t): pack structure
Reduces rb_io_t from 200 to 192 bytes, allowing rb_io_t to
occupy one less cache line.
[Feature #10050]
n.b. this leaves a 4-byte hole after the `cbuf' field which may
be used for future expansion.

* include/ruby/io.h (rb_io_t): shrink to 200 bytes from 216 on 64-bit
This puts us within 8 bytes of being three cache lines instead of
four lines on x86-64. This breaks the ABI.
[Feature #10050]

* include/ruby/oniguruma.h (struct re_pattern_buffer): shrink to 448
bytes from 464 bytes on 64-bit. This breaks the ABI.
[Feature #10034]
Reducing struct re_pattern_buffer from 464 to 448 bytes allows it to fit
into neatly into seven 64-byte cache lines on x86-64 systems.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46881 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

the equality, otherwise the behavior is undefined.

* configure.in (with-jemalloc): also check for header, for ABIs
which JEMALLOC_MANGLE is needed, i.e., Mach-O and PE-COFF
platforms. [ruby-core:62939] [Feature #9113]
* include/ruby/missing.h: include alternative malloc header to
replace memory management functions.
* dln.c, io.c, parse.y, st.c: undef malloc family before
re-definition to suppress warnings.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46354 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* encoding.c: move `ruby_encoding_index` stuff from
include/ruby/encoding.h to hide the extra field.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46323 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
This is too new to be a compatibility problem.
* include/ruby/ruby.h: Hide Symbol internals.
(struct RSymbol): moved to internal.h
(RSYMBOL): ditto
