gallivm: Fix saturated signed psub/padd intrinsics on llvm 8

LLVM 8 did remove both the signed and unsigned sse2/avx intrinsics in
the end, and provide arch-independent llvm intrinsics instead.
Fixes a crash when using snorm framebuffers (tested with piglit
arb_color_buffer_float-render GL_RGBA8_SNORM -auto).
