S/390: Fix rounding for _Decimal128 to _Decimal32 conversion

We do not have a direct conversion instruction from 128 bit DFP to 32
bit DFP so this needs to be done in two steps.  The first needs to be
done with the "prepare for shorter precision rounding mode" in order
to produce a correct result.

S/390: Define macros for rounding mode constants

This patch replaces a few magic numbers used for floating point
rounding modes with macros.  This is mostly a NoOp change apart from:

fixuns_truncdddi2, fixuns_trunctddi2, fixuns_trunc<mode>si2: Replace 5
with DFP_RND_TOWARD_0 (which is 9).

5 as well as 9 represent round towards 0 with the difference that for
5 the new DFP quantum exception is enabled as well.  This exception
isn't IEEE754 and we do not have an interface to enable and test it
anyway.  So we do not intend to enable it.  This so far should not
have any noticable effect since the quantum exception was not
observable through the Posix functions.

Some pattern ("fix_trunc<mode>di2") is already using rounding mode 9
correctly.

PR c++/70105: prevent nonsensical underline spew for macro expansions

diagnostic_show_locus can sometimes do the wrong thing when handling
expressions built up from macros.

PR c++/70105 (currently marked as a P3 regression) has an example of
a diagnostic where over 500 lines of irrelevant source are printed,
and underlined, giving >1000 lines of useless spew to stderr.

This patch adds extra sanitization to diagnostic-show-locus.c, so that
we only attempt to print underlines and secondary locations if such
locations are "sufficiently sane" relative to the primary location
of a diagnostic.

This "sufficiently sane" condition is implemented by a new helper
function compatible_locations_p, which requires such locations to
have the same macro expansion hierarchy as the primary location,
using linemap_macro_map_loc_unwind_toward_spelling, effectively
mimicing the expansion performed by LRK_SPELLING_LOCATION.

This may be too strong a condition, but it effectively fixes
PR c++/70105, without removing any underlines in my testing.

Successfully bootstrapped&regrtested in combination with the previous
