Adam Nemet 8ae70506ea [Disasm][AVX512] Implement decoding of top bit for non-destructive reg fields 
V' bit in the P2 byte of the EVEX prefix provides the top bit of the NDD and
NDS register fields.  This was simply not used in the decoder until now.

Fixes <rdar://problem/17402661>

Patrik Hagglund 319983810a Fix gcc -Wsign-compare warning in X86DisassemblerTables.cpp. 
X86_MAX_OPERANDS is changed to unsigned.

Also, add range-based for loops for affected loops. This in turn
needed an ArrayRef instead of a pointer-to-array in
InternalInstruction.

Richard Smith 5d50610306 C++ has a bool type! (And C's had one too, for 15 years...)

Richard Smith ac15f1cda3 Don't provide two different definitions of ModRMDecision, OpcodeDecision, and ContextDecision in different source files (depending on #define magic).

Richard Smith 89ee75d786 What year is it! This file has no reason to be written in C, and has doubly no 
reason to expose a global symbol 'decodeInstruction' nor to pollute the global
scope with a bunch of external linkage entities (some of which conflict with
others elsewhere in LLVM).

This is just the initial transition to C++; more cleanups to follow.
