ira.c combine_and_move_insns, and ordering of functions
Notes added by add_store_equivs are not used directly or indirectly by
combine_and_move_insns. add_store_equivs can therefore run later
without affecting the output of combine_and_move_insns, and thus
add_store_equivs need not take into account potentially moved insns.
Since not all potentially combined/moved insns are in fact combined or
moved, this may allow add_store_equivs to add more REG_EQUIV notes.
grow_reg_equivs isn't needed until the reload reg_equivs array is
changed.
ira.c (combine_and_move_insns): Move invariant conditions..
(ira.c): ..to here. Call combine_and_move_insns before
add_store_equivs. Call grow_reg_equivs later. Allocate
req_equiv later using max_reg_num() rather than global max_regno.
(contains_replace_regs): Delete.
(add_store_equivs): Remove contains_replace_regs test.
