gcc uses trap 33 for profiling, but the simulator didn't support it.

Browse Source 
This patch fixes the gcc.dg/nest.c failures for sh-elf.

Fri Oct 11 16:22:28 2002  J"orn Rennecke <joern.rennecke@superh.com>

	* interp.c (trap): Return int.  Take extra parameter for address
	of the trap instruction.  Changed all callers.
	Add case 33 for profiling.
	* gencode.c (trapa): Handle trap 33 using the trap function.
	Add read of vector for generic traps.
