nobu fa8b08b424 Prefer `rb_fstring_lit` over `rb_fstring_cstr`
The former states explicitly that the argument must be a literal,
and can optimize away `strlen` on all compilers.

normal 4f53579896 load.c: use ruby_sized_xfree for calloc-ed RArray VALUE
IMHO, this increases readability, too, since it's not
immediately clear that the object is on the malloc heap
and not a regular Ruby object.

tenderlove bf04b4e188 load.c: reduce memory usage of loaded_features_index
Use integer hashsum instead of string as a key in loaded_features_index.
Do not use ruby strings for substring operation, just plain pointer
and length.

normal 903b6628de load.c: use rb_warning directly
This removes the last dependency on rb_mWarning outside of
error.c and allows future commits to mark it static.

Yes, I expect this to slow down the emitting of a warning
message in a cold code path slightly :P

mame 620ba74778 Manage AST NODEs out of GC
NODEs in AST are no longer objects managed by GC.  This change will
remove the restriction imposed by the GC.  For example, a NODE can use
more than five words (this is my primary purpose; we want to store the
position data for each NODE, for coverage library), or even a NODE can
have variable length (some kinds of NODEs have unused fields).
To do this, however, we need more work, since Ripper still uses T_NODE
objects managed by the GC.

The life time of NODEs is more obvious than other kinds of objects; they
are created at parsing, and they become disused immediately after
compilation.  This change releases all NODEs by a few `xfree`s after
compilation, so performance will be improved a bit.  In extreme example,
`eval("x=1;" * 10000000)` runs much faster (40 sec. -> 7.8 sec. on my
machine).

The most important part of this change is `ast_t` struct, which has
three contents: (1) NODE buffer (malloc'ed memory), (2) a reference to
the root NODE, and (3) an array that contains objects that must be
marked during parsing (such as literal objects).  Some functions that
had received `NODE*` arguments, must now receive `ast_t*`.

* node.c, node.h: defines `ast_t` struct and related operations.
* gc.c, internal.h: defines `imemo_ast`.
* parse.y: makes `parser_params` struct have a reference to `ast_t`.
  Instead of `rb_node_newnode`, use `rb_ast_newnode` to create a NODE.
* iseq.c, load.c, ruby.c, template/prelude.c.tmpl: modifies some
  functions to handle `ast_t*` instead of `NODE*`.
* test/ruby/test_gc.rb: ad-hoc fix for a failed test.  The test assumes
  GC eden is increased at startup by NODE object creation.  However,
  this change now create no NODE object, so GC eden is not necessarily
  increased.

ko1 837fd5e494 Use rb_execution_context_t instead of rb_thread_t
to represent execution context [Feature #14038]

* vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer.
  There are many code using `th` to represent execution context
  (such as cfp, VM stack and so on). To access `ec`, they need to
  use `th->ec->...` (adding one indirection) so that we need to
  replace them by passing `ec` instead of `th`.

  remove `ruby_current_thread` global variable.

ko1 2108e55c0b use "enum ruby_tag_type" and TAG_NONE.
Return value of EXEC_TAG() is saved by "int state".
Instead of "int", use "enum ruby_tag_type". First EXEC_TAG()
value should be 0, so that define TAG_NONE (= 0) and use it.

Some code used "status" instead of "state". To make them clear,
rename them to state.

We can change variable name from "state" to "tag_state", but this
ticket doesn't contain it.

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.

Running: valgrind -v ruby -rrdoc -rubygems -e exit
shows a minor memory reduction (32-bit userspace)

before:

  in use at exit: 1,600,621 bytes in 28,819 blocks
total heap usage: 55,786 allocs, 26,967 frees, 6,693,790 bytes allocated

after:

  in use at exit: 1,599,778 bytes in 28,789 blocks
total heap usage: 55,739 allocs, 26,950 frees, 6,692,973 bytes allocated

Reduce cognitive overhead, eye strain and keep lines less than 80
columns to benefit users of giant fonts (honestly I prefer 64 column
wrap :P).

nobu bcba951320 load.c: avoid segfault when 'throw' occurs in the middle of rb_load_file_str
How can a 'throw' happen while the current thread is reading a Ruby source file
from disk and parsing it? It can happen if another thread calls Thread#raise,
and passes an Exception object which responds to #exception, and the custom #exception
method calls Kernel#throw.

In practice, this is most likely to happen if you combine the use of autoload and
Timeout.timeout.

An extra check is required to avoid a segfault in this case.

* load.c (rb_load_internal0): extra check before returning TAG_RAISE when a
  non-local transfer of control happens while loading and parsing a Ruby source file.
