Hi all,

Looking at calls.c:initialize_argument_information, I spotted some dead
code that seems to have been left behind from when MPX support was
removed.

This patch removes that code as well as the associated target hooks
(which appear to be unused).

Bootstrapped and regtested on aarch64-linux-gnu and x86_64-linux-gnu, no
regressions.

OK for trunk?

Thanks,
Alex
