Add a new gdbarch method to resolve the address of TLS variables.
Permit TLS variable addresses to be resolved purely by an ABI rather
than requiring a target method. This doesn't try the target method if
the ABI function is present (even if the ABI function fails) to
simplify error handling.
gdb/ChangeLog:
* gdbarch.sh (get_thread_local_address): New method.
* gdbarch.h, gdbarch.c: Regenerate.
* target.c (target_translate_tls_address): Use
gdbarch_get_thread_local_address if present instead of
target::get_thread_local_address.
