YJIT: Initialize locals in ISeqs defined with `...` (#12660)
* YJIT: Fix indentation [ci skip]
Fixes: cdf33ed5f37f9649c482c3ba1d245f0d80ac01ce
* YJIT: Initialize locals in ISeqs defined with `...`
Previously, callers of forwardable ISeqs moved the stack pointer up
without writing to the stack. If there happens to be a stale value in
the area skipped over, it could crash due to "try to mark T_NONE". Also,
the uninitialized local variables were observable through `binding`.
Initialize the locals to nil.
[Bug #21021]
