This is part of a series of changes to enable generating more
efficient code for C++ "noexcept" functions. See also the RFC,
https://discourse.llvm.org/t/rfc-add-call-unwindabort-to-llvm-ir/62543

The 'unwindabort' modifier on "resume" specifies that execution should
abort in a personality-function-defined manner, instead of continuing
execution in the caller.

This commit adds only the core textual and bitcode IR parsing/writing
for the 'resume' instruction.

Depends on D141913 <https://reviews.llvm.org/D141913>
