x86-64/Intel: fix CALL/JMP with dword operand
While dc2be329b950 ("i386: Only check suffix in instruction mnemonic")
has made the assembler accept these in the first place (they were wrongly
rejected before), the generated code was still wrong in that it lacked
an operand size override. (In 64-bit code, other than in 16- and 32-bit
ones, CALL and JMP with memory operands are all entirely unambiguous: No
operand size can have two meanings.)
