gallivm: Fix lerping of (un)signed normalized numbers.
Several issues actually:
- Fix a regression in unsigned normalized in the rescaling
[0, 255] to [0, 256]
- Ensure we use signed shifts where appropriate (instead of
unsigned shifts)
- Refactor the code slightly -- move all the logic inside
lp_build_lerp_simple().
This change, plus an adjustment in the tolerance of signed normalized
results in piglit fbo-blending-formats fixes bug 57903
