Fix some JIT disassembly issues
Fix some JIT disassembly issues

1. (v)movsd operands were messed up in disassembly:
vmovsd   qword ptr [rsp+28H]ymm0, qword ptr
instead of
vmovsd   qword ptr [rsp+28H], ymm0

2. cvtxx2yy insructions had GPR names prefixed with x/y:
vcvtsi2ss ymm0, yrcx
vcvttss2si yrsi, ymm6
