YJIT: Initialize locals in ISeqs defined with ... (#12660)
YJIT: Fix indentation [ci skip]

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.
