Map CORINFO_HELP_THROWEXACT to THROW (#121579)

MichalStrehovsky · web-flow · commit a2b94d3bddeb · 2025-11-13T21:59:56.000+01:00
This is temporary. It will not do the right thing wrt exception stack at
runtime, but it's better than crashing at compile time (which is what it
does now).

Not filing a bug on this; we either fix this before we start running the
tests or hit it during test async bringup (I assume there's a test) and
then ActiveIssue it as needed.
