[1/2] m32c: Don't use set_optab_handler

Committed after a build completed.


r~


	* config/m32c/m32c.c (TARGET_INIT_LIBFUNCS): Remove.
	(m32c_init_libfuncs): Remove.
	* config/m32c/cond.md (cstore<QHPSI>4_16): Rename from cstore<QHPSI>4.
	(cstore<QHPSI>4): New expander.

I tried to test this, but newlib won't build (looks unrelated).  The
failure is this assert in expmed.h:


  gcc_assert (to_mode >= MIN_MODE_INT
	      && to_mode <= MAX_MODE_INT
	      && from_mode >= MIN_MODE_INT
	      && from_mode <= MAX_MODE_INT);

which can't possibly work on any platform with partial int modes
(PSImode) because the P*modes are enumerated *after* the regular
integer modes, so PSImode's enum value is higher than TImode
(MAX_MODE_INT for m32c).  Should there be a range check for
MIN,MAX_MODE_PARTIAL_INT as well?

enum machine_mode
{
  VOIDmode,                /* machmode.def:173 */
  BLKmode,                 /* machmode.def:177 */
  CCmode,                  /* machmode.def:205 */
  BImode,                  /* machmode.def:180 */
  QImode,                  /* machmode.def:185 */
  HImode,                  /* machmode.def:186 */
  SImode,                  /* machmode.def:187 */
  DImode,                  /* machmode.def:188 */
  TImode,                  /* machmode.def:189 */
  PSImode,                 /* config/m32c/m32c-modes.def:26 */
