[PATCH] D125647: [ARM SEH 5] [MC] [Win64EH] Check that the SEH unwind opcodes match the actual instructions

[Martin Storsjö via Phabricator via llvm-commits]

mstorsjo added a comment.

Added checks to make sure that prologs and epilogs are properly terminated, and epilog start/end are paired correctly. This gives clearer indication if there were issues in code generation (like epilogs being mangled by tail merging).
