Reid Kleckner ec4d326aad Fix miscompile of MS inline assembly with stack realignment ... For stack frames requiring realignment, three pointers may be needed: - ebp to address incoming arguments - esi (could be any callee-saved register) to address locals - esp to address outgoing arguments We would use esi unconditionally without verifying that it did not conflict with inline assembly. This change doesn't do the verification, it simply emits a fatal error on functions that use stack realignment, dynamic SP adjustments, and inline assembly. Because stack realignment is common on Windows, we also no longer assume that MS inline assembly clobbers esp. Instead, we analyze the inline instructions for implicit definitions and check if esp is there. If so, we require the use of a base pointer and consider it in the condition above. Mostly fixes PR16830, but we could try harder to find a non-conflicting base pointer.
