[PATCH,testsuite] skip two tests with -mlongcall on powerpc targets

[-- Attachment #1: Type: text/plain, Size: 517 bytes --]

The attached patch skips two tests on powerpc targets if -mlongcall is
in effect.  Essentially, if -mlongcall is in effect, then we place
function addresses into the CTR register and bctrl instead of calling
the function directly, as the tests expect.

Tested on powerpc64-unknown-linux-gnu and powerpc-wrs-vxworks.  OK to
commit?

	* gcc.dg/tree-ssa/loop-1.c: Skip on powerpc targets if -mlongcall.
