30954527b7 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.

991995c4e7 xtensa: fix _Unwind_GetCFA 
Returning context->cfa in _Unwind_GetCFA makes CFA point one stack frame
higher than what was actually used by code at context->ra. This results
in invalid CFA value in signal frames and premature unwinding completion
in forced unwinding used by uClibc NPTL thread cancellation.
Returning context->sp from _Unwind_GetCFA makes all CFA values valid and
matching code that used them.
