8b2bf5ed88 Add Power8 SHA support 
This provides the functions needed for an implementation. It does not provide the implementation itself

Enable little endian Rijndael_UncheckedSetKey_POWER8 using built-ins 
The problem was vec_sld is endian sensitive. The built-in required more than us setting up arguments to ensure the vsx load resulted in a big endian value. Thanks to Paul R on Stack Overflow for sharing the information that IBM did not provide. Also see http://stackoverflow.com/q/46341923/608639

Add Power8 key expansion for big endian 
This is AES-128 key expansion for big endian. Little endian has a bug in it so it can't be enabled at the moment. GDB is acting up on GCC112, so I've had trouble investigating it

Add CRYPTOPP_NO_CPU_FEATURE_PROBES (GH #511) 
We determine machine capabilities by performing an os/platform *query* first, like getauxv(). If the *query* fails, we move onto a cpu *probe*. The cpu *probe* tries to exeute an instruction and then catches a SIGILL on Linux or the exception EXCEPTION_ILLEGAL_INSTRUCTION on Windows. Some OSes fail to hangle a SIGILL gracefully, like Apple OSes. Apple machines corrupt memory and variables around the probe.

Refactor LoadT() and StoreT(). Add separate ReverseT() for little endian machines 
The refactoring has no effect on little endian machines. However, on big endian GCC119 using GCC 7.1 the performance improved by 2.5x for ECB and CTR modes:
