aarch64 SFrame: skip with warning new CFI directive used with pauth_lrHEADmaster
Today, SFrame v2 specification does not describe how to encode the information corresponding to the PAuth_LR PAC signing method (it only supports PAuth PAC signing method). SFrame v3 specification should hopefully specify it. In the meantime, if the GNU assembler finds .cfi_negate_ra_state_with_pc and --gsframe is specified, it will output a warning to the user and will fail to generate the FDE entry. A new SFrame test for .cfi_negate_ra_state_with_pc is also added to reflect this issue. Approved-by: Indu Bhagat <indu.bhagat@oracle.com>
