aarch64: Fix _BitInt testcases
This patch fixes some testisms introduced by:
commit 5aa3fec38cc6f52285168b161bab1a869d864b44

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.
