[Clang] Fix segmentation fault caused by `VarBypassDetector` stack overflow on deeply nested expressions (#124128)
This happens when using `-O2`.
Similarly to #111701
([test](https://github.com/bricknerb/llvm-project/blob/93e4a7386ec897e53d7330c6206d38759a858be2/clang/test/CodeGen/deeply-nested-expressions.cpp)),
not adding a test that reproduces since this test is slow and likely to
be hard to maintained as discussed here and in [previous
discussion](https://github.com/llvm/llvm-project/pull/111701/files/1a63281b6c240352653fd2e4299755c1f32a76f4#r1795518779).
Test that was reverted here:
