aarch64: Fix _BitInt testcases

     aarch64: Add support for _BitInt

The testcases were relying on an unnecessary sign-extend that is no longer
generated.

The tested version was just slightly behind top of trunk when the patch
was committed, and the codegen had changed, for the better, by then.

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/bitfield-bitint-abi-align16.c (g1, g8, g16, g1p, g8p,
	g16p): Remove unnecessary sbfx.
	* gcc.target/aarch64/bitfield-bitint-abi-align8.c (g1, g8, g16, g1p, g8p,
	g16p): Likewise.
