aarch64: skip copy of RA state register into target context
The RA state register is local to a frame, so it should not be copied to
the target frame during the context installation.
This patch adds a new backend handler that check whether a register
needs to be skipped or not before its installation.
libgcc/ChangeLog:
* config/aarch64/aarch64-unwind.h
(MD_FRAME_LOCAL_REGISTER_P): new handler checking whether a register
from the current context needs to be skipped before installation into
the target context.
(aarch64_frame_local_register): Likewise.
* unwind-dw2.c (uw_install_context_1): use MD_FRAME_LOCAL_REGISTER_P.
