1312b1ba11 As part of the final cleanup of aarch64_internal_mov_immediate a return was accidentally removed. 
As part of the final cleanup of aarch64_internal_mov_immediate a return was
accidentally removed.  This causes the 2-instruction case to fallthrough
into the general case even when it found a match.  An example immediate is
0xcccccccccccccccd which was using 2 instructions in GCC5 but now requires 4.
Adding the return fixes the regressions.
