Fix some testcases after my computed goto patch

For some reason I did not see these failures in my testing.
Sorry about that.  Anyways this fixes the testcases by
adding a cast to __INTPTR_TYPE__ and then a cast to void*.

Committed after testing them on x86_64-linux-gnu.

gcc/testsuite/ChangeLog:

	* gcc.c-torture/compile/920826-1.c: Fix computed goto.
	* gcc.c-torture/compile/pr27863.c: Likewise.
