There was a problem hiding this comment.
We previously needed to these transition blocks when splitting after a BBJ_COND. Since removing its implicit fallthrough behavior, we no longer create transition blocks here.

Late follow-up to #71273. I noticed
fgRelocateEHRegionscurrently never tries to move handler regions (even if we aren't doing hot/cold splitting) becausefgDetermineFirstColdBlockmust keep handler entries hot, which is no longer true. I plan to enable that functionality in the next PR; for now, this cleans up all the dead code around HANDLER_ENTRY_MUST_BE_IN_HOT_SECTION. This should be a no-diff change.cc @dotnet/jit-contrib, @AndyAyersMS PTAL. Thanks!
