The format_warning_at_substring API has a rather clunk way of indicating
the location of the pertinent param (if any): a source_range * is passed
in, which can be NULL. Doing so requires extracting a range from the
location_t and passing around a pointer to it, or NULL, as needed.
This patch simplifies things by eliminating the source_range * in
favor of a location_t, with UNKNOWN_LOCATION used to signify that
no param location is available.
gcc/c-family/ChangeLog:
* c-format.c (format_warning_at_char): Pass UNKNOWN_LOCATION
rather than NULL to format_warning_va.
(check_format_types): Likewise when calling format_type_warning.
Remove code to extract source_ranges and source_range * in favor
of just a location_t.

location_t.
gcc/ChangeLog:
* gimple-ssa-sprintf.c (fmtwarn): Update for changed signature of
format_warning_at_substring.

source_range * in favor of just a location_t.

This is a version of the patch posted by Trevor Saunders on 2017-07-31,
for which he wrote:

> The changes are mostly s/gdb/gtl/g
This version was updated by me (dmalcolm) adding these changes:
- renaming of "gtl" to "gnu" (3 letters, and one of the ones Richi
proposed, and not a match for "*tl")
- renaming of DEFINE_GDB_UNIQUE_PTR to DEFINE_GNU_UNIQUE_PTR
- renaming of xfree_deleter to xmalloc_deleter, and making it
use "free" rather than "xfree" (which doesn't exist)
- added a gcc/unique-ptr-tests.cc
- implement unique_xmalloc_ptr<T[]> (taken from gdb, but changing
"xfree" to "free", and adding support for pre-C++-11)

DSP instructions are optional for Arm Cortex-M33, yet its -mcpu option
does not allow +nodsp. Users are thus left with using
-march=armv8-m.main -mtune=cortex-m33. This patch allows +nodsp to
-mcpu=cortex-m33.

Fix PR82442
Recently the gcc.dg/vect/pr31699.c was modified to check for
vect_float effective target instead for vect_double. As a
result it now fails on armhf. Fix by avoiding double.
Tested on armhf, aarch64 and x64.
