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

In <https://gcc.gnu.org/ml/gcc-bugs/2016-08/msg03233.html>, Nick
reported i386-elf and ia64-elf failing to build because of
float128_type_node being NULL, but being used by the back end for
__float128.

The global float128_type_node is only available conditionally, if
target hooks indicate TFmode is not only available as a scalar mode
and of the right format, but also supported in libgcc.  The back-end
support, however, expects the type always to be available for
__float128 even if the libgcc support is missing.

Although a target-specific node could be restored in the case where
libgcc support is missing, it seems better to address the missing
libgcc support.  Thus, this patch enables TFmode soft-fp in libgcc
globally for all x86 targets - the only special cases needed being for
targets that use soft-fp for SFmode and DFmode, one of which already
had the support for TFmode as well (so I based the i[34567]86-*-rtems*
configuration on that present for i[34567]86-*-elfiamcu).  The i386
implementation of TARGET_LIBGCC_FLOATING_MODE_SUPPORTED_P is then
removed as no longer needed.

I can provide such a patch for ia64 if useful, but am not in a
position to test it (and while I'm reasonably confident that enabling
this support would be right for ia64-elf and ia64-freebsd, I've no
real idea if enabling libgcc support for TFmode, with or without also
enabling it for XFmode, would be safe for ia64-vms).

Bootstrapped with no regressions on x86_64-pc-linux-gnu.
