Extend this attribute to cover long double ABIs, for 64-bit too.
This patch also corrects an error that crept in to code setting
rs6000_passes_float. See the added comment. Passing IEEE128 values
in vsx regs ought to set both Tag_GNU_Power_ABI_FP and
Tag_GNU_Power_ABI_Vector. Also adds a new option, default on, that
disables output of .gnu_attribute assembly directives.

<https://gcc.gnu.org/ml/gcc-patches/2006-03/msg00541.html>, which
inadvertently made the registers covered to be referred to as "address"

TS 18661-1 defines <limits.h> and <stdint.h> macros for widths of
standard integer types and the typedefs defined in, or whose limits
are defined in, <stdint.h>. (The connection to the main
floating-point subject matter of TS 18661-1 is that these are intended
to be used with the fromfp functions to convert from floating point to
integer types of any width in any rounding direction, though these
macros may be of more general use.)
This patch implements support for these macros in GCC's <limits.h> and
<stdint.h>. To avoid needing to implement fixincludes for system
headers where GCC wraps the system libc's <stdint.h> in hosted mode,
the test for the <stdint.h> macros uses -ffreestanding (I'll add the
macros to glibc's headers separately) - but as usual for new features
in these headers, platforms (primarily OpenBSD) that use USER_H to
avoid using GCC's headers at all will have failures until the system
headers have the feature added or appropriate fixincludes are
implemented.
The header macros are implemented using appropriate new predefined
macros, with the code avoiding defining more such macros than
necessary (so one predefined macro suffices for corresponding signed
and unsigned types, while no such predefined macros are needed for the
exact-width types such as int8_t).
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

Previous, fix-it hints were printed using the color of the severity
of the diagnostic (magenta for warnings, red for errors, cyan for
notes).
This patch updates fix-it hints so that replacement text is printed in
green, to better distinguish the suggested improvement from
the current code. For example:
spellcheck-fields.cc:52:13: error: 'struct s' has no member named 'colour'; did you mean 'color'?
return ptr->colour; <<< RED
^~~~~~ <<< RED
color <<< GREEN
It makes sense for the underlinings that indicate deletions to
be printed in red, so the patch changes that also. For example:
diagnostic-test-show-locus-color.c:179:9: warning: example of a removal hint
int a;; <<< MAGENTA
^ <<< MAGENTA
- <<< RED

MULTILIB_OPTIONS should be used.
2016-08-24 Thomas Preud'homme <thomas.preudhomme@arm.com>
* doc/fragments.texi (MULTILIB_REUSE): Mention that only options in
MULTILIB_OPTIONS should be used. Small wording fixes.
* genmultilib: Memorize set of all option combinations in
combination_space. Detect if RHS of MULTILIB_REUSE uses an option not
found in MULTILIB_OPTIONS by checking if option set is listed in
combination_space. Output new and existing error message to stderr.
