When producing error and warning messages, libgfortran writes a
message by using many system calls. By using vectored writes (the
POSIX writev function) when available and feasible to use without
major surgery, we reduce the chance that output gets intermingled with
other output to stderr.
In practice, this is done by introducing a new function estr_writev in
addition to the existing estr_write. In order to use this, the old
st_vprintf is removed, replaced by direct calls of vsnprintf, allowing
more message batching.

In r262891 I reimplemented this call:
dump_printf_loc (MSG_NOTE, loc, "=== %s ===\n", name);
in dump_begin_scope to use direct calls to dump_loc:
if (dump_file)
{
dump_loc (MSG_NOTE, dump_file, loc.get_location_t ());
fprintf (dump_file, "=== %s ===\n", name);
}
if (alt_dump_file)
{
dump_loc (MSG_NOTE, alt_dump_file, loc.get_location_t ());
fprintf (alt_dump_file, "=== %s ===\n", name);
}
However ::dump_loc doesn't filter with pflags and alt_flags.
This lead to stray output of the form:
test.cpp:1:6: note: test.cpp:1:11: note:
when using -fopt-info with "optimized" or "missed".
This patch adds this missing filtering, eliminating the stray partial
note output.

The Fortran front-end has a bug in which it uses "int" values for "size_t"
parameters. I don't know why this isn't problem for all 64-bit architectures,
but GCN ends up with the data in the wrong argument register and/or stack slot,
and bad things happen.
This patch corrects the issue by setting the correct type.

At present, pointers passed to builtin functions, including atomic operators,
are stripped of their address space properties. This doesn't seem to be
deliberate, it just omits to copy them.
Not only that, but it forces pointer sizes to Pmode, which isn't appropriate
for all address spaces.
This patch attempts to correct both issues. It works for GCN atomics and
GCN OpenACC gang-private variables.
