Don't enable GC.auto_compact in EnvUtil.under_gc_compact_stress when not supported

Fix compile issue with a short-circuited if/unless condition and `defined?`

2024-09-30T17:12:56+00:00

This caused an issue when `defined?` was in the `if` condition. Its
instructions weren't appended to the instruction sequence even though it was compiled
if a compile-time known logical short-circuit happened before the `defined?`. The catch table
entry (`defined?` compilation produces a catch table entry) was still on the iseq even though the
instructions weren't there. This caused faulty exception handling in the method.
The solution is to no add the catch table entry for `defined?` after a compile-time known logical
short circuit.

This shouldn't touch much code, it's only for cases like the following,
which can occur during debugging:

    if false && defined?(Some::CONSTANT)
    "more code..."
    end

Support `GC.auto_compact = :empty` on debug builds

2023-12-19T23:29:36+00:00

This commit adds `GC.auto_compact = :empty` which will run
auto-compaction sorting pages by empty slots so the most amount of
objects will be moved. This will make it easier to write tests for
auto-compaction.

Fix compaction during ary_make_partial

2023-11-27T17:40:26+00:00

The ary_make_shared call may allocate, which can trigger a GC
compaction. This can cause the array to be embedded because it has a
length of 0.

Prefer RbConfig.ruby over the 3.times fallback (#8691)

2023-10-18T00:57:39+00:00

It seems saner to use RbConfig.ruby than using ruby in a random ancestor
directory.
