Update soft-fp from glibc

- Subject: Update soft-fp from glibc
- Authentication-results: sourceware.org; auth=none
This patch updates soft-fp in libgcc from glibc. The motivation for
this late update is the recent change of MIPS to use soft-fp: the
update brings in the new support for after-rounding tininess
detection, without which MIPS TFmode operations would have started
raising underflow exceptions in certain cases where they should not be
raised on after-rounding architectures such as MIPS, and would not
previously have been raised (because of the use of fp-bit), a
technical regression that would cause issues for enabling testing
rounding modes and exceptions for MIPS long double in glibc. The only
other soft-fp changes are to copyright dates.
The _FP_TININESS_AFTER_ROUNDING settings in sfp-machine.h for
architectures not supported by glibc have not been checked, and have
comments to that effect - but since none of the unchecked
architectures actually have any support in libgcc for generating
hardware exceptions from software floating point, there is no
observable effect of any inaccuracy in the choice of setting (which in
any case is only meaningful if the architecture defines this choice at
all - i.e. if it has some form of hardware floating point, but soft-fp
is being used for operations or types not supported in hardware).
__float128 testcases are added that illustrate on x86 / x86_64 / ia64
what has been fixed (IEEE 754-2008 requires the choice of tininess
detection to be the same for all binary operations, so it was a bug
that __float128 previously used before-rounding tininess detection
when hardware floating point used after-rounding on those
architectures).
Bootstrapped with no regressions on x86_64-unknown-linux-gnu. Applied
to mainline.
