[fr30] Fix indirect_jump pattern


The pattern was accepting a nonimediate_operand, using the C condition
to weed out certain types of memory, but was then using an "r" constraint
to force a register.  This patch makes the predicate match the constraint
and removes the C condition.

Tested by building fr30-elf and using:

int
foo (int i)
{
  __typeof(&&a) foo[] = { &&a, &&a, &&b, &&c };

 restart:
  goto *foo[i];

 a:
  return 1;

 b:
  i += 1;
  goto restart;

 c:
  return 2;
}

to triger an indirect jump (checked via -dp).  OK to install?

Thanks,
Richard

	* config/fr30/fr30.md (indirect_jump): Use pmode_register_operand
	instead of nonimmediate_operand.  Remove C condiition.
