Re: testsuite: Adjust target requirements for sad-vectorize and signbit

Fixes
FAIL: gcc.target/powerpc/signbit-1.c scan-assembler-not stxvd2x
FAIL: gcc.target/powerpc/signbit-1.c scan-assembler-times mfvsrd 3
FAIL: gcc.target/powerpc/signbit-1.c scan-assembler-times srdi 3
FAIL: gcc.target/powerpc/signbit-2.c scan-assembler-times ld 1
FAIL: gcc.target/powerpc/signbit-2.c scan-assembler-times srdi 1
on powerpc-linux (or powerpc64-linux biarch -m32).

signbit-1.c is quite obviously a 64-bit only testcase given the
scan-assembler directives, and the purpose of the testcase to verify
the 64-bit only UNSPEC_SIGNBIT patterns.  It could be made to pass for
-m32 by adding -mpowerpc64, but that option that isn't very effective
when bi-arch testing and results in errors on rs6000-aix.  And it is
pointless to match -m32 stores to the stack followed by loads, which
is what we do at the moment.

signbit-2.c on the other hand has more reasonable 32-bit output.

	* gcc.target/powerpc/signbit-1.c: Reinstate lp64 condition.
	* gcc.target/powerpc/signbit-2.c: Match 32-bit output too.
