x86_64: Correct THREAD_SETMEM/THREAD_SETMEM_NC for movq [BZ #27591]
config/i386/constraints.md in GCC has (define_constraint "e" "32-bit signed integer constant, or a symbolic reference known to fit that range (for immediate operands in sign-extending x86-64 instructions)." (match_operand 0 "x86_64_immediate_operand")) Since movq takes a signed 32-bit immediate or a register source operand, use "er", instead of "nr"/"ir", constraint for 32-bit signed integer constant or register on movq.
