Enable Intel WAITPKG instructions. 

Intel has disclosed a set of new instructions for Tremont processor.
The spec is
https://software.intel.com/en-us/intel-architecture-instruction-set-extensions-programming-reference
This patch enables Intel WAITPKG instructions.

opcodes/
	* i386-dis.c (enum): Add PREFIX_MOD_0_0FAE_REG_6,
	PREFIX_MOD_1_0FAE_REG_6.
	(va_mode): New.
	(OP_E_register): Use va_mode.
	* i386-dis-evex.h (prefix_table):
	New instructions (see prefixes above).
