i386: Clear vex instead of vex.evex
"vex" has many fields to control how to decode an instruction. Clear
all fields in "vex" before decoding an instruction to avoid using values
left from the previous instruction.

* testsuite/gas/i386/prefix.s: Add tests for vcvtpd2dq with
VEX and EVEX prefixes.
* testsuite/gas/i386/prefix.d: Updated.

PR binutils/23025
* i386-dis.c (get_valid_dis386): Don't set vex.prefix nor vex.w
to 0.
(print_insn): Clear vex instead of vex.evex.
