Add ss/sd suffix to InstX8632Store and legalize FP constants.

InstX8632Store is essentially a "mov" and it would emit
a mov, but it did not add the ss/sd suffix based on the operand type.

Also, there are some cases where legalization would leave
two memory operands in the case that one of them
is a floating point immediate:

storeDoubleConst:
.LstoreDoubleConst$entry:
  mov     eax, dword ptr [esp+4]
  mov     qword ptr [eax], qword ptr [L$double$1]
  ret
