* Test fix ARM headers
This problem has been festering for some time. The header file includes are slightly different than the ISA options. Some platforms need an include, others don't.
* Fix cryptest-android.sh and cryptest-ios.sh
* Fix MSVC ARM32 and ARM64 compile
* Split ARM32 and ARM64 recipes in GNUmakefile
Use PowerPC unaligned loads and stores with Power8. Formerly we were using Power7 as the floor because the IBM POWER Architecture manuals said unaligned loads and stores were available. However, some compilers generate bad code for unaligned loads and stores using `-march=power7`, so bump to a known good.
Some comments in config.h were old. Time for a refresh.
Switch from CRYPTOPP_BOOL_ARM64 to CRYPTOPP_BOOL_ARMV8. Aarch32 is ARMv8, and that's the important part.
GCM can do some bulk XOR's using the SIMD unit. However, we still need loads and stores to be fast. Fast loads and stores of unaligned data requires the VSX unit
