Summary

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 specifies that if the call stack is unwound
due to an exception, the personality function should abort the process
instead of continuing to unwind to the caller.

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