(reg_used_between_after_reload_p): Likewise.
(reg_set_or_used_since_bb_start): Likewise.
(eliminate_partially_redundant_load): Use reg_changed_after_insn_p

Use reg_set_between_p instead of reg_set_between_after_reload_p.
* rtlanal.c (reg_set_p): Check whether REG overlaps
regs_invalidated_by_call, rather than just checking the
membership of REGNO (REG).
