  This is actually a composite test that checks the behaviour of both the
.cfi_negate_ra_state and .cfi_b_key_frame directives on aarch64.

ChangeLog:

	* testsuite/gas/cfi-sframe/cfi-sframe-aarch64-pac-ab-key-1.d:
	New test.
	* testsuite/gas/cfi-sframe/cfi-sframe-aarch64-pac-ab-key-1.s:
	Likewise.
	* testsuite/gas/cfi-sframe/cfi-sframe.exp: Run new test.
