This gets rid of the need for multiple inheritance, and better
reflects the design - a Guard isn't an instance of GuardByte or
InitByte, it meerly uses them.

This is the 6th of 6 changes to overhaul cxa_guard.
See D108343 <https://reviews.llvm.org/D108343> for what the final result will be and more details on why
cxa_guard is getting overhauled.

Depends on D110101 <https://reviews.llvm.org/D110101>
