[InstCombine] Canonicalize SPF to abs intrinsic ...

This patch enables canonicalization of SPF_ABS and SPF_ABS
to the abs intrinsic.

This is a recommit, the original try was
05d4c4ebc2fb006b8a2bd05b24c6aba10dd2eef8,
but it was reverted due to an apparent miscompile,
which since then has just been fixed by the previous commit.
