[JSC] Do stack check on IPInt->BBQ loop OSR entry
https://bugs.webkit.org/show_bug.cgi?id=307229
rdar://169866596
Reviewed by Yusuke Suzuki.
IPInt->BBQ loop reuses the IPInt frame, but BBQ frames may use more space.
Currently we check for stack overflow and crash, instead of ahead of time. This
PR changes the behavior to stay in IPInt if we don't have enough stack space.
This check existed in the old WasmLLInt but wasn't ported over to IPInt.
