This patch adds 2 tests to the testsuite to make sure the -mupper-regs-df and
-mupper-regs-sf options work, and you can generate add, subtract, multiply,
divide, and compare instructions on scalars living in the Altivec registers.  I
also fixed the p8vector-ldst.c test, which has been broken for some time (this
test was a preliminary test for the upper regs support).

Assuming the previous patches are checked in, is this patch ok to install?

	* gcc.target/powerpc/p8vector-ldst.c: Rewrite to use 40 live
	floating point variables instead of using asm to test allocating
	values to the Altivec registers.

	* gcc.target/powerpc/upper-regs-sf.c: New -mupper-regs-sf and
	-mupper-regs-df tests.
	* gcc.target/powerpc/upper-regs-df.c: Likewise.
