  This patch fixes some testisms introduced by:

commit 5aa3fec38cc6f52285168b161bab1a869d864b44
Author: Andre Vieira <andre.simoesdiasvieira@arm.com>
Date:   Wed Apr 10 16:29:46 2024 +0100

     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.

OK for trunk? (I am away tomorrow, so if you want this in before the 
weekend feel free to commit it on my behalf, if approved ofc...)


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.

LGTM, thanks.  Pushed to trunk.
