Make the following primops take a third (initial) argument to
indicate the rounding mode to use, like their scalar cousins do:
Iop_Add32Fx4 Iop_Sub32Fx4 Iop_Mul32Fx4 Iop_Div32Fx4
Iop_Add64Fx2 Iop_Sub64Fx2 Iop_Mul64Fx2 Iop_Div64Fx2
Iop_Add64Fx4 Iop_Sub64Fx4 Iop_Mul64Fx4 Iop_Div64Fx4
Iop_Add32Fx8 Iop_Sub32Fx8 Iop_Mul32Fx8 Iop_Div32Fx8
Fix up the x86 and amd64 front ends to add fake rounding modes
(Irrm_NEAREST) when generating expressions using these primops.
Fix up the x86 and amd64 back ends to accept these as triops
rather than as binops, and ignore the first arg.
Add three more ir_opt folding rules to remove memcheck
instrumentation arising from instrumentation of known-defined
rounding modes.
Overall functional and performance effects should be zero.
