cmd/asm: enable MOVSD in the encoding end-to-end test
MOVSD is properly handled but its encoding test wasn't enabled. Enable
it.
For reference this was found with a little tool I wrote [1] to explore
which instructions are missing or not tested in the go obj package and
assembler:
"which SSE2 instructions aren't tested? And don't list instructions
which can take MMX operands"
$ x86db-gogen list --extension SSE2 --not-tested --not-mmx
CLFLUSH mem [m: np 0f ae /7] WILLAMETTE,SSE2
MOVSD xmmreg,xmmreg [rm: f2 0f 10 /r] WILLAMETTE,SSE2
MOVSD xmmreg,xmmreg [mr: f2 0f 11 /r] WILLAMETTE,SSE2
MOVSD mem64,xmmreg [mr: f2 0f 11 /r] WILLAMETTE,SSE2
MOVSD xmmreg,mem64 [rm: f2 0f 10 /r] WILLAMETTE,SSE2
(CLFLUSH was introduced with SSE2, but has its own CPUID bit)
