[Feature #6047]
Currently it's grown by `BUFSIZ` (1024) on every iteration which is bit wasteful.
Instead we can double the capacity whenever there is less than `BUFSIZ` capacity
left.
... to prevent "circular require" when `--disable-gems` is used.
This is a simplified case of e5a0abc5de
```
$ bundle exec ruby -we 'system("ruby", "-w", "--disable-gems", "-e", "")'
<internal:/home/mame/work/ruby/local/lib/ruby/3.2.0+3/rubygems/core_ext/kernel_require.rb>:85: warning: <internal:/home/mame/work/ruby/local/lib/ruby/3.2.0+3/rubygems/core_ext/kernel_require.rb>:85: warning: loading in progress, circular require considered harmful - /home/mame/work/ruby/local/lib/ruby/3.2.0+3/bundler/setup.rb
```
When bundler/setup is require'ed under --disable-gems mode, it loads
rubygems by `require "rubygems" unless defined?(Gem)` in
0b1f682a6d/bundler/lib/bundler/rubygems_integration.rb (L3)
In this case, require'ing bundler/setup from rubygems.rb is circular.
This change makes rubygems.rb to require "bundler/setup" only when
`Bundler` is not defined.

This SyntaxError#path feature only exists in Ruby HEAD. Until it is released in a preview I want to continue to support existing releases of 3.2.0 (and also so CI will continue to work, as it still uses a preview version to execute tests).

By moving the two bools into a packing gap above the mark_bits
pointer/union we can save 8 bytes in the struct and avoid an extra cache
line (328 bytes vs 320 bytes).

In 274870bd5434ab64ac3a3c9db9aa27d262c1d6d6 we gained the ability to
make an educated guess at the max_iv_count of a class based on its
initialize method. This commit makes subclasses inherit their super's
max_iv_count, which makes the estimate work in cases that the subclass
does not have an initialize method.
Previously, the frozen check happened on `RCLASS_ORIGIN(self)`, which
can return an iclass. The frozen check is supposed to respond to objects
that users can call methods on while iclasses are hidden from users.
Other mutation methods like Module#{define_method,alias_method,public}
don't do this. Check frozen status on the module itself.
Fixes [Bug #19164] and [Bug #19166].

The MarkDown parser in RDoc requires 4 columns indentation for
paragraphs following list items. Otherwise, the following paragraphs
are not interpreted as the part of the preceeding list item,
struct_ivar_get recently started using rb_class_superclass to
resolve super instead of RCLASS_SUPER. This change made
Qnil a possible case we need to return from within the
struct_ivar_get for loop.
Calling `String#scan` without a block creates an incomplete MatchData
object whose `RMATCH(match)->str` is Qfalse. Usually this object is not
leaked, but it was possible to pull it by using ObjectSpace.each_object.
This change hides the internal MatchData object by using rb_obj_hide.
Fixes [Bug #19159]
Previously we essentially never freed block even after invalidation.
Their reference count never reached zero for a couple of reasons:
1. `Branch::block` formed a cycle with the block holding the branch
2. Strong count on a branch that has ever contained a stub never
reached 0 because we increment the `.clone()` call for
`BranchRef::into_raw()` didn't have a matching decrement.
It's not safe to immediately deallocate blocks during
invalidation since `branch_stub_hit()` can end up
running with a branch pointer from an invalidated branch.
To plug the leaks, we wait until code GC or global invalidation and
deallocate the blocks for iseqs that are definitely not running.
When we run global invalidation for TracePoints or code GC, we clear out
all blocks in our assumptions table but we don't deallocate the backing
buffers. Let's reclaim some memory during these rare events.
HashSet::clear() doesn't deallocate the backing buffer and shrink the
capacity. Replace with a 0-capcity set instead so we reclaim some memory
each code GC.
