gallivm: Generalize lp_build_mul and lp_build_lerp for signed normalized
types.
This fixes fdo <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - [llvmpipe] src/gallium/auxiliary/gallivm/lp_bld_arit.c:1051:lp_build_lerp: Assertion `!type.sign' failed."
href="show_bug.cgi?id=57755">bug 57755</a> and most of the failures of piglit
fbo-blending-formats
GL_EXT_texture_snorm.
GL_INTENSITY_SNORM is still failing, but problem is probably elsewhere,
as GL_R8_SNORM works fine.
