* alias.c (nonlocal_reference_p): Minor reformatting.
* reload.c (find_equiv_reg): Simplify logic for
CALL_INSN_FUNCTION_USAGE since can't have SUBREG or pseudos and
some some reformatting.
* reload1.c (reload_combine): Don't assume everything in
CALL_INSN_FUNCTION_USAGE is a REG and clean up code a bit.
