gallivm: fix lp_build_compare_ext

Browse source 
The expansion should always be to the same width as the input arguments
no matter what, since these functions should work with any bit width of
the arguments (the sext is a no-op on any sane simd architecture).
Thus, fix the caller expecting differently.
