Move from 'static' to 'enum' for class constants
...
Enums don't take up space in class objects. Its should result in smaller objects and faster code

Clear Coverity UNINIT (CID 171239)

It was a false positive, but dark and silent cockpits trump the uneeded initialization. The optimizer can remove it.

Updated static initializers
...
When MSVC init_seg or GCC init_priority is available, we don't need to use the Singleton. We only need to create a file scope class variable and place it in the segment for MSVC or provide the attribute for GCC.
An additional upside is we cleared all the memory leaks that used to be reported by MSVC for debug builds.

Add GCC inline ASM for PMULL and PMULL2
...
The macros that invoke GCC inline ASM have better code generation and speedup GCM ops by about 70 MiB/s on an Opteron 1100. The intrinsics are still available for Windows platforms and Visual Studio 2017 and above

Breakout __ARM_FEATURE_CRYPTO into PMULL, AES and SHA for Apple Clang (Issue 362)
...
It appears Apple Clang disgorges carryless multiply (PMULL) from Crypto (AES and SHA). The breakout added CRYPTOPP_BOOL_ARM_PMULL_INTRINSICS_AVAILABLE for PMULL, and retained CRYPTOPP_BOOL_ARM_CRYPTO_INTRINSICS_AVAILABLE for AES and SHA only

Add CC clobber to cpuid call
...
This should not be needed, but it does not hurt. According to Ian Lance Taylor (http://gcc.gnu.org/ml/gcc-help/2014-02/msg00023.html ), the CC clobber causes GCC to forget its internal representation of flag state. It should not be needed for cpuid. However, Clang has some odd behave in a couple of versions of its compiler when using cpuid. Both JW and UB experienced it on separate occassions.
