This commit should contain all the necessary boilerplate to make the
8.8-A architecture exist from LLVM and Clang's point of view: it adds
the new arch as a subtarget feature, a definition in TargetParser, a
name on the command line, an appropriate set of predefined macros, and
adds appropriate tests. The new architecture name is supported in both
AArch32 and AArch64.

However, in this commit, no actual _functionality_ is added as part of
the new architecture. If you specify -march=armv8.8a, the compiler
will accept it and set the right predefines, but generate no code any
differently.
