Cleanup Altivec and Power7 code paths 
This changes the dependency from Altivec to Power7. Internally we needed Power7 but it was cut-in as a pseudo Altivec dependency. Also see http://groups.google.com/forum/#!topic/cryptopp-users/fmEKOG41SG8

Detect XSAVE/XRESTORE OS feature support (GH #521) 
This avoids the probe for SSE2 in most circumstances. The SSE2 test is mostly benign nowadays since SSE2 and OS support is nearly ubiquitous. But the define CRYPTOPP_NO_CPU_FEATURE_PROBES added for Apple OSes was interacting badly on x86 machines. Also see GH #511.

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.

Route Borland/Embarcadero into MS inline ASM code for CPUID 
The inline ASM code now uses local variables to save the EAX-EDX registers, and then copies the locals into the function parameters. It side steps problems with calling conventions

7851a0d510 Remove BOOL macro value (GH #462) 
Currently the CRYPTOPP_BOOL_XXX macros set the macro value to 0 or 1. If we remove setting the 0 value (the #else part of the expression), then the self tests speed up by about 0.3 seconds. I can't explain it, but I have observed it repeatedly.
This check-in prepares for the removal in Upstream master

Fix NEON detection on Aarch32 and Aarch64 
I wish GCC would get its head out of its ass and define the apprpriate defines. NEON/ASIMD cannot be disgorged from Aarch32/Aarch64 just like SSE2 cannot be disgorged from x86_64. They are core instruction sets

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.

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.
