Fix disassembling of PAUSE instruction. Fixes PR10900. Also fixed NOP disassembling to ignore OpSize and REX.W.

Make IC_VEX* not inherit from IC_*. Prevents instructions with no VEX form from disassembling to their non-VEX form. Also prevents weak filter collisons that were keeping valid VEX instructions from decoding properly. Make VEX_L* not inherit from VEX_* because the VEX.L bit always important. This stops packed int VEX encodings from being disassembled when specified with VEX.L=1. Fixes PR10831 and PR10806.

Add vvvv support to disassembling of instructions with MRMDestMem and MRMDestReg form. Needed to support mem dest form of vmaskmovps/d. Fixes PR10807.

Give ATTR_VEX higher priority when generating the disassembler context table. Fixes disassembling of VEX instructions with 'pp'=00. Fixes subset of PR10678.

Add TB encoding to VEROALL, VZEROUPPER, and VCVTPS2PD to allow them to be disassembled. Fixes PR10723.

VEX prefixes are working for triadic AVX
instructions.  This concludes the patch set to
enable AVX support for the X86 disassebler.

of the instruction leading to improper decoding of
certain instructions with the 66H prefix.  Also added
a test case for this.

compensate, unbreaking disassembly of lea's.

Updated the disassembler to support this unified register set.
Added a testcase to verify that the registers continue to be
decoded correctly.
