* vm_core.h: remove `rb_execution_context_t::passed_bmethod_me`
and fix functions to pass the `me` directly.
`passed_bmethod_me` was used to make bmethod (methods defined by
`defined_method`). `rb_vm_invoke_bmethod` invoke `Proc` with `me`
information as method frame (`lambda` frame, actually).
If the proc call is not bmethod call, `passed_bmethod_me` should
be NULL. However, there is a bug which passes wrong `me` for
normal block call.
http://ci.rvm.jp/results/trunk-asserts@silicon-docker/1449470
This is because wrong `me` was remained in `passed_bmethod_me`
(and used incorrectly it after collected by GC).
We need to clear `passed_bmethod_me` just after bmethod call,
but clearing is not enough.
To solve this issue, I removed `passed_bmethod_me` and pass `me`
information as a function parameter of `rb_vm_invoke_bmethod`,
`invoke_block_from_c_proc` and `invoke_iseq_block_from_c` in vm.c.
* vm.c (invoke_iseq_block_from_c): the number of parameters is too
long so that I try to specify `ALWAYS_INLINE`.
* vm.c (invoke_block_from_c_proc): ditto.
* vm_insnhelper.c (vm_yield_with_cfunc): now there are no pathes
to use bmethod here.

When EMPTY_OR_DELETED_BIN_P(bin) is true, it is a wrong idea to
subtract ENTRY_BASE from it. Delay doing so until we are sure to be
safe.

Before this changeset RHASH_ARRAY_SIZE_DEC() was expaneded to include
an expression like `RHASH_ARRAY_SIZE+(-1)`. RHASH_ARRAY_SIZE is by
definition unsigned int. -1 is signed, of course. Adding a signed
and an unsigned value requires the "usual arithmetic conversions" (cf:
ISO/IEC 9899:1990 section 6.2.1.5). -1 is converted to 0xFFFF by that.
This patch prevents that conversion.

* vm_core.h (rb_thread_struct): introduce new fields `invoke_type`
and `invoke_arg`.
There are two types threads: invoking proc (normal Ruby thread
created by `Thread.new do ... end`) and invoking func, created
by C-API. `invoke_type` shows the types.
* thread.c (thread_do_start): copy `invoke_arg.proc.args` contents
from Array to ALLOCA stack memory if args length is enough small (<8).
We don't need to keep Array and don't need to cancel using transient heap.
* vm.c (thread_mark): For func invoking threads, they can pass (void *)
parameter (rb_thread_t::invoke_arg::func::arg). However, a rubyspec test
(thread_spec.c) passes an Array object and it expect to mark it.
Clealy it is out of scope (misuse of `rb_thread_create` C-API). However,
I'm not sure someone else has such kind of misunderstanding.
So now we mark conservatively this (void *) arg with rb_gc_mark_maybe.
This misuse is found by this error log.

maybe after bundler introduction to this repository, we randomly hit
errors like:
http://ci.rvm.jp/results/trunk-gc-asserts@silicon-docker/1447918
As we would require minitest in this repository anyway, it should be
fine to suppress the error there.

Dir.each on an internal method encapsulated on a private class
`Entry_#entry`, having no '.' neither '..' entries would make
now superfluous a chained reject filtering.
This change can improve the performance of these FileUtils
methods when the provided path covers thousands of files or
directories:
- chmod_R
- chown_R
- remove_entry
- remove_entry_secure
- rm_r
- remove_dir
- copy_entry

r65577 seems to have made MJIT_CC (MJIT_CC_COMMONA) become an absolute
path. So start_process doesn't need to find that from PATH by dln_find_exe_r.

In these expressions `1` is of type `signed int` (cf: ISO/IEC
9899:1990 section 6.1.3.2). The variable (e.g. `num`) is of type
`rb_num_t`, which is in fact `unsigned long`. These two expressions
then exercises the "usual arithmetic conversions" (cf: ISO/IEC
9899:1990 section 6.2.1.5) and both eventually become `unsigned long`.
The two unsigned expressions are then subtracted to generate another
unsigned integer expression (cf: ISO/IEC 9899:1990 section 6.3.6).
This is where integer overflows can occur. OTOH the left hand side of
the assignments are `rb_snum_t` which is `signed long`. The
assignments exercise the "implicit conversion" of "an unsigned integer
is converted to its corresponding signed integer" case (cf: ISO/IEC
9899:1990 section 6.2.1.2), which is "implementation-defined" (read:
not portable).
Casts are the proper way to avoid this problem. Because all
expressions are converted to some integer types before any binary
operations are performed, the assignments now have fully defined
behaviour. These values can never exceed LONG_MAX so the casts must
not lose any information.

Unaligned word access warnings generated by UBSAN are often
treated well already, depending on this macro.

Looking at the lines right above, it is clear than a blue sky
that we cannot assume `p` to be aligned at all when
UNALIGNED_WORD_ACCESS is true. It is a wrong idea to use
__builtin_assume_aligned for that situation.

Integer overflow for unsigned types are fully defined in C. They
are not always problematic (but not always OK). These functions
in this changeset intentionally utilizes that behaviour.
Blacklist from UBSAN checks for better output.
