5c: dont substibute (destination) registers contained in MOVM reglist
this fixes the miscompilation of 6l with 5c resulting in bogus
vlong -> long conversion at the top of asmandsz():
asmandsz 0x0000aec4 MOVW.W R14,#-0x2c(R13)
asmandsz+0x4 0x0000aec8 MOVW rex+8(FP),R5
asmandsz+0x8 0x0000aecc MOVW $andptr-SB(SB),R7
asmandsz+0xc 0x0000aed0 MOVW R0,R6
asmandsz+0x10 0x0000aed4 AND $#0x44,R5,R8
asmandsz+0x14 0x0000aed8 MOVW R8,rex+8(FP)
asmandsz+0x18 0x0000aedc MOVW R0,R4
asmandsz+0x1c 0x0000aee0 MOVM.IA (R0),[R1,R3] <- R1 used here
asmandsz+0x20 0x0000aee4 MOVW R8,v-4(SP) <- substituted by R8
