Hi!
As usually, Apple dwarf tools crash when seeing the new extensions
and I forgot to guard all their output with !dwarf_strict (if it is accepted
for DWARF 5 it will of course be changed into
dwarf_version >= 5 || !dwarf_strict).
Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
tested on a short testcase that with -gstrict-dwarf we don't emit
any of them. Ok for trunk?

* dwarf2out.c (mem_loc_descriptor) <case ENTRY_VALUE>: Return NULL
if dwarf_strict.
(gen_subprogram_die): Don't add call_site DIEs if dwarf_strict.
Clear call_arg_locations and call_arg_loc_last always.
