[Committed] [spu] Fix asm gotos

[Andrew Pinski]

Hi,
  The problem here is that the back-end function, get_branch_target
was not ready for a JUMP instruction to contain inline-asm.  This
causes a crash as single_set would return NULL.  This patch fixes the
problem by returning NULL for ASM_OPERANDS.

Committed after a build/test for spu-elf with no regressions and the
asmgoto* testcases working.

Thanks,
Andrew Pinski

ChangeLog:
* spu.c (get_branch_target): Return NULL for ASM_OPERANDS patterns.
