Created attachment 24977
  --> https://bugs.llvm.org/attachment.cgi?id=24977&action=edit
failed case

Found when trying to compile newlib.
LLVM is on the branch official/release/12.x
I tried the commit in the main branch:
9872551ca09b David Green        o [ARM] Skip debug during vpt block creation
but its not helpful.

I think ConvertVPTBlocks should also skip debug instructions at around line
1527.
