gas: sframe: add support for .cfi_b_key_frame
Gather the information from the DWARF FDE on whether frame's return
addresses are signed using the B key or A key. Reflect the information in
the SFrame counterpart data structure, the SFrame FDE.
ChangeLog:
* gas/gen-sframe.c (get_dw_fde_pauth_b_key_p): New definition.
(sframe_v1_set_func_info): Add new argument for pauth_key.
(sframe_set_func_info): Likewise.
(output_sframe_funcdesc): Likewise.
* gas/gen-sframe.h (struct sframe_version_ops): Add new argument
to the function pointer declaration.
* gas/sframe-opt.c (sframe_convert_frag): Handle pauth_key.
