* optabs.c: Remove unnecessary forward declarations.
(expand_unop_direct): New, broken out of expand_unop.
(expand_doubleword_clz): New.
(expand_ctz): Move above expand_ffs. Use
start_sequence, end_sequence, add_equal_note, and
expand_unop_direct. Add more commentary.
(expand_ffs): Try both ctz optab and expand_ctz.
Generate a test and branch if the hardware doesn't give us
a useful value for input zero. Style improvements similar to
expand_ctz.
* config/arm/arm.md (ffssi2, ctzsi2): Delete.
