* config/m32c/shift.md: Rewrite: Allow arbitrary operands for
shift counts, separate SI shifts for m32c vs m16c, pass shift type
so that constant shifts can be split.
* config/m32c/m32c.c (m32c_const_ok_for_constraint_p): Add In6.
(m32c_valid_pointer_mode): Make static.
(shift_gen_func_for): New.
(m32c_prepare_shift): Use it. Split large const shifts into
multiple shifts.
* config/m32c/predicates.md (shiftcount_operand): Allow more
general operands.
(longshiftcount_operand): New.
* doc/md.texi (Machine Constraints): Document In6.

* intrinsics/c99_functions.c: Add function prototypes to avoid
warnings from -Wstrict-prototypes -Wmissing-prototypes. On Tru64
work around a brain-dead libm by redirecting calls to cabs{,f,l}
to a local __gfc_cabs{,f,l}.

(mark_threaded_blocks, register_jump_thread): New functions.
(thread_through_all_blocks): Remove unwanted argument. No
longer rely on e->aux to communicate thread target info.
Call mark_threaded_blocks. Release the threaded_blocks
bitmap and threaded_edges vector when complete.

(threaded_blocks): Remove.
(tree_ssa_dominator_optimize): Remove initialization and
finalization of threaded_blocks. Simplify call to

used to communicate with thread_through_all_blocks.
