    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.
