Update soft-fp from glibc. 

This patch updates the soft-fp code in libgcc from glibc.  There are
no changes here of significance to the use of soft-fp in GCC (and so
no testsuite additions); it's simply an update to bring in the latest
soft-fp version (which will also hopefully go into Linux 4.4 to
replace the 15-year-old copy currently in Linux).

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