JIT: Clamp basic block IL ranges when splitting blocks (#89179)

In release, code motion/compaction may lead to statements ending up in
blocks that don't contain their IL offset. This can cause splitting of
blocks to create meaningless IL ranges such as [057..020). Since we
maintain these IL ranges on a best-effort basis, just clamp them when we
do the splitting.

Fix #88348
