libgcc: Split FDE search code from PT_GNU_EH_FRAME lookup
This allows switching to a different implementation for
PT_GNU_EH_FRAME lookup in a subsequent commit.
This moves some of the PT_GNU_EH_FRAME parsing out of the glibc loader
lock that is implied by dl_iterate_phdr. However, the FDE is already
parsed outside the lock before this change, so this does not introduce
additional crashes in case of a concurrent dlclose.
libgcc/ChangeLog:
* unwind-dw2-fde-dip.c (struct unw_eh_callback_data): Add hdr.
Remove func, ret.
(find_fde_tail): New function. Split from
_Unwind_IteratePhdrCallback. Move the result initialization
from _Unwind_Find_FDE.
(_Unwind_Find_FDE): Updated to call find_fde_tail.
