Subject: Patch committed: Set arg_pointer_save_area_init

The arg_pointer_save_area_init field of the rtl_data structure is
currently read-only.  It's use suggested that the intention is for it to
be set to true when the argument pointer save area has been initialized,
but that is not actually done.  This patch fixes that.  Bootstrapped and
tested on x86_64-unknown-linux-gnu.  Committed as obvious.
