PREFIX_EVEX_0F2E, PREFIX_EVEX_0F2F): Delete.
(prefix_table): Add EXxEVexS operand to vcvttss2si, vcvttsd2si,
vcvtss2si, vcvtsd2si, vucomiss, and vucomisd table entries.
Retain X macro and PREFIX_OPCODE use from tjhe EVEX table for
the latter two.
* i386-dis-evex.h (evex_table): Reference VEX table for opcodes
0F2C, 0F2D, 0F2E, and 0F2F.
