rs6000: Extend 20050603-3.c testcase to 64-bit

The testcase used to fail on 64-bit, but it was disabled there.
This patch makes it run there, and beefs up the checking of the
generated code a bit.

	* gcc.target/powerpc/20050603-3.c: Don't restrict to ilp32.  Do more
	tests for the expected generated code.
