Previously protected methods on refinements could never be called
because they were seen as being "defined" on the hidden refinement
ICLASS.
This commit updates calling refined protected methods so that they are
considered to be defined on the original class (the one being refined).
This ended up using the same behaviour that was used to check whether a
call to super was allowed, so I extracted that into a method.

Commit 0c36ba53192c5a0d245c9b626e4346a32d7d144e changed GC compaction
methods to not be implemented when not supported. However, that commit
only does compile time checks (which currently only checks for WASM),
but there are additional compaction support checks during run time.
This commit changes it so that GC compaction methods aren't defined
during run time if the platform does not support GC compaction.

This function was added to a public header in [1] probably
unintentionally since it's not used anywhere, exposes implementation
details, and isn't related to the goals of that pull request.

* Added a nil check in Net::HTTPHeader#initialize_http_header for keys in the header that do not have any value
* Returning nil from the content_range method instead of raising an error when the unit in the content-range header is not bytes
* Modified initialize_http_header to match trunk

rb_backtrace relies on the existend of RUBY_T_MASK. This is set up by
the global loading code in lldb_init()
rb_backtrace does not call lldb_init previously, and therefore would
only work if called after another lldb function that _did_ load the
globals.
Now that classes are using VWA, the RCLASS_PTR uses an offset to get the
rb_classext_t object. Doing this all the time in lldb is boring. So
script lldb to do it for us
The `asdf-ruby` plugin sets `RUBYLIB` to require some code to reshim
after installing gems. This interferes with our specs.
Reset that, but leave any "internal" entries in places, because the
ruby-core test setup also uses RUBYLIB.

I tried to build Ruby on a system without libyaml today and realized
that my attempt from <https://github.com/ruby/psych/pull/557> doesn't
fix the error in <https://github.com/ruby/psych/issues/552>. I still got
the same `LoadError` from `digest` which stopped the build.
Since `LoadError` is not a `StandardError`, a plain `rescue` doesn't catch
it. Catch `LoadError` explicitly instead and reduce the scope of the
`begin` block.
I tested this change in a Ruby build on macOS without libyaml installed
and confirmed that `make` continues with a warning instead of aborting:
*** Following extensions are not compiled:
psych:
Could not be configured. It will not be installed.

This should address <https://bugs.ruby-lang.org/issues/18790>.

This commit makes YJIT allocate memory for generated code gradually as
needed. Previously, YJIT allocates all the memory it needs on boot in
one go, leading to higher than necessary resident set size (RSS) and
time spent on boot initializing the memory with a large memset().
Users should no longer need to search for a magic number to pass to
`--yjit-exec-mem` since physical memory consumption should now more
accurately reflect the requirement of the workload.
YJIT now reserves a range of addresses on boot. This region start out
with no access permission at all so buggy attempts to jump to the region
crashes like before this change. To get this hardening at finer
granularity than the page size, we fill each page with trapping
instructions when we first allocate physical memory for the page.
Most of the time applications don't need 256 MiB of executable code, so
allocating on-demand ends up doing less total work than before. Case in
point, a simple `ruby --yjit-call-threshold=1 -eitself` takes about
half as long after this change. In terms of memory consumption, here is
a table to give a rough summary of the impact:
| Peak RSS in MiB | -eitself example | railsbench once |
| :-------------: | ---------------: | --------------: |
| before | 265 | 377 |
| after | 11 | 143 |
| no YJIT | 10 | 101 |
A new module is introduced to handle allocation bookkeeping.
`CodePtr` is moved into the module since it has a close relationship
with the new `VirtualMemory` struct. This new interface has a slightly
smaller surface than before in that marking a region as writable is no
longer a public operation.
