Update soft-fp from glibc (PR libgcc/77265).

Browse Source 
This patch updates soft-fp from glibc, bringing in the fix for PR
libgcc/77265, XFmode extension to TFmode wrongly turning an infinity
into a NaN.  A test for that bug is added.

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

	PR libgcc/77265

	* gcc.dg/torture/float128-extend-inf.c: New test.
