pa.c (output_mul_insn): Delete nop after branch in template...

Browse Source 
* pa.c (output_mul_insn): Delete nop after branch in template,
	conditionally emit a nop if the delay slot was not filled. (via %#)

	* pa.c (output_function_prologue): Handle profiling in a function
	without a frame pointer.
