[ARM] Adding macros for coprocessor intrinsics as per ACLE

[tmatheson]

Summary

Patch by Ranjeet Singh and Son Tuan Vu.

[tmatheson]

Add 8.8 and 9.3; patches adding these were merged first in the end.

Combine V8 and V9 macros

[vhscampos]

clang/lib/Basic/Targets/ARM.cpp

925–945

Consider merging these two if statements.

Is v8.1-M not included on purpose?
