Fix ICE.

Fix ICE.  Need use VOID instead of SI, or when real VOIDmode comes, it does not
match SImode, so cause issue.

2014-09-25  Chen Gang  <gang.chen.5i5j@gmail.com>

gcc:
	* config/microblaze/microblaze.md (call_internal1): Use VOID
	instead of SI to fix "((void (*)(void)) 0)()" issue
gcc/testsuite:
	* gcc.c-torture/compile/calls-void.c: New test.
