cmd/compile: use unsigned constant when folding loads for SIMD ops with constants

When folding loads into a SIMD op with a constant, in the SSA
rules we use makeValAndOff to create an AuxInt for the constant
and the offset. For the SIMD ops of concern (for now), the
constants are always unsigned. So pass the constant unsigned.

Fixes #76756.
