This commit changes RUBY_GC_HEAP_INIT_SIZE_{40,80,160,320,640}_SLOTS to
RUBY_GC_HEAP_{0,1,2,3,4}_INIT_SLOTS. This is easier to use because the
user does not need to determine the slot sizes (which can vary between
32 and 64 bit systems). They now just use the heap names
(`GC.stat_heap.keys`).
In general, if the same option specifying a single value is given
multiple times at the same level, the last one overrides the earlier
ones, unless prohibited.
There’s no reason to prevent RUBYOPT from controlling the backtrace
limit. In fact, Matz said [0] he was expecting this to be possible.

Introduce Universal Parser mode for the parser.
This commit includes these changes:
* Introduce `UNIVERSAL_PARSER` macro. All of CRuby related functions
are passed via `struct rb_parser_config_struct` when this macro is enabled.
* Add CI task with 'cppflags=-DUNIVERSAL_PARSER' for ubuntu.
Instead of `rb_fork`, to update `current_fork_gen` which has been
introduced at 3563e1383f.
Otherwise, the forked process attempts to stop the timer thread, but
raises an exception because the thread is not alive in the child and
dies because already no tag is present at that time.

RB_WARN_CATEGORY_ALL_BITS is exposed in a public header, so it
makes sense for it to be updated to contain all valid bits.
Instead we introduce RB_WARN_CATEGORY_DEFAULT_BITS to list the
categories that are enabled by default.
[Feature #19538]
This new `peformance` warning category is disabled by default.
It needs to be specifically enabled via `-W:performance` or `Warning[:performance] = true`
Add a sampling option to trace exits
Running YJIT with trace exits enabled can make very large metrics files.
This allows us to configure a sample rate to make tracing exits possible
on larger tests. This also updates the documented YJIT options.

Remove !USE_RVARGC code
[Feature #19579]
The Variable Width Allocation feature was turned on by default in Ruby
3.2. Since then, we haven't received bug reports or backports to the
non-Variable Width Allocation code paths, so we assume that nobody is
using it. We also don't plan on maintaining the non-Variable Width
Allocation code, so we are going to remove it.
This reverts commit 35136e1e9c.
test-spec has been failing since this revision.

```
When loading Ruby source files, we can save the result of
successful opens as open(2)/openat(2) are a fairly expensive
syscalls. This also avoids a time-of-check-to-time-of-use
(TOCTTOU) problem.
This reduces open(2) syscalls during `require'; but should be
most apparent when users have a small $LOAD_PATH. Users with
large $LOAD_PATH will benefit less since there'll be more
open(2) failures due to ENOENT.
With `strace -c -e openat ruby -e exit' under Linux, this
results in a ~14% reduction of openat(2) syscalls
(glibc uses openat(2) to implement open(2)).
% time seconds usecs/call calls errors syscall
------ ----------- ----------- --------- --------- ----------------
0.00 0.000000 0 296 110 openat
0.00 0.000000 0 254 110 openat
Additionally, the introduction of `struct ruby_file_load_state'
may make future optimizations more apparent.
This change cannot benefit binary (.so) loading since the
dlopen(3) API requires a filename and I'm not aware of an
alternative that takes a pre-existing FD. In typical
situations, Ruby source files outnumber the mount of .so
files.
Tested on production workloads at Shopify for > 1 year and proven
to be quite stable. Enabling YJIT at run-time is still guarded
behind the --yjit command-line option for now.
Raise a `SyntaxError` with the parser error message, in the case
reading from a file instead of the `-e` option or standard input. So
syntax_suggest can get the message from the caught error.
