Minor tweak to LowerUINT_TO_FP_i32. Bias (after scalar_to_vector) has two uses so we should make it the second source operand of ISD::OR so 2-address pass won't have to be smart about commuting.

The reason 2-addr pass isn't smart enough to commute the ORPSrr is because it can't look pass the MOVSD2PDrr instruction.

Implement a special algorithm for converting uint_to_fp for i32 values on
...
X86. This code:
void f() {
uint32_t x;
float y = (float)x;
}
used to be:
movl %eax, -8(%ebp)
movl [2^52 double], -4(%ebp)
movsd -8(%ebp), %xmm0
subsd [2^52 double], %xmm0
cvtsd2ss %xmm0, %xmm0
Is now:
movsd [2^52 double], %xmm0
movsd %xmm0, %xmm1
movd %ecx, %xmm2
orps %xmm2, %xmm1
subsd %xmm0, %xmm1
cvtsd2ss %xmm1, %xmm0
This is faster on X86. Note that there's an extra load of %xmm0 into %xmm1. That
will be fixed in a later coalescer fix.

- i64 mul is now a legal instruction, but emits an instruction sequence

several small countries and most southern US states (just kidding, but
looking at a function with 80+ parameters is really weird and just plain
wrong.)

pointer elimination. However since they were marked as implicitly using
SP they could not be rematerialised.
