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. * soft-fp/adddf3.c: Update from glibc. * soft-fp/addsf3.c: Likewise. * soft-fp/addtf3.c: Likewise. * soft-fp/divdf3.c: Likewise. * soft-fp/divsf3.c: Likewise. * soft-fp/divtf3.c: Likewise. * soft-fp/double.h: Likewise. * soft-fp/eqdf2.c: Likewise. * soft-fp/eqsf2.c: Likewise. * soft-fp/eqtf2.c: Likewise. * soft-fp/extenddftf2.c: Likewise. * soft-fp/extended.h: Likewise. * soft-fp/extendsfdf2.c: Likewise. * soft-fp/extendsftf2.c: Likewise. * soft-fp/extendxftf2.c: Likewise. * soft-fp/fixdfdi.c: Likewise. * soft-fp/fixdfsi.c: Likewise. * soft-fp/fixdfti.c: Likewise. * soft-fp/fixsfdi.c: Likewise. * soft-fp/fixsfsi.c: Likewise. * soft-fp/fixsfti.c: Likewise. * soft-fp/fixtfdi.c: Likewise. * soft-fp/fixtfsi.c: Likewise. * soft-fp/fixtfti.c: Likewise. * soft-fp/fixunsdfdi.c: Likewise. * soft-fp/fixunsdfsi.c: Likewise. * soft-fp/fixunsdfti.c: Likewise. * soft-fp/fixunssfdi.c: Likewise. * soft-fp/fixunssfsi.c: Likewise. * soft-fp/fixunssfti.c: Likewise. * soft-fp/fixunstfdi.c: Likewise. * soft-fp/fixunstfsi.c: Likewise. * soft-fp/fixunstfti.c: Likewise. * soft-fp/floatdidf.c: Likewise. * soft-fp/floatdisf.c: Likewise. * soft-fp/floatditf.c: Likewise. * soft-fp/floatsidf.c: Likewise. * soft-fp/floatsisf.c: Likewise. * soft-fp/floatsitf.c: Likewise. * soft-fp/floattidf.c: Likewise. * soft-fp/floattisf.c: Likewise. * soft-fp/floattitf.c: Likewise. * soft-fp/floatundidf.c: Likewise. * soft-fp/floatundisf.c: Likewise. * soft-fp/floatunditf.c: Likewise. * soft-fp/floatunsidf.c: Likewise. * soft-fp/floatunsisf.c: Likewise. * soft-fp/floatunsitf.c: Likewise. * soft-fp/floatuntidf.c: Likewise. * soft-fp/floatuntisf.c: Likewise. * soft-fp/floatuntitf.c: Likewise. * soft-fp/gedf2.c: Likewise. * soft-fp/gesf2.c: Likewise. * soft-fp/getf2.c: Likewise. * soft-fp/ledf2.c: Likewise. * soft-fp/lesf2.c: Likewise. * soft-fp/letf2.c: Likewise. * soft-fp/muldf3.c: Likewise. * soft-fp/mulsf3.c: Likewise. * soft-fp/multf3.c: Likewise. * soft-fp/negdf2.c: Likewise. * soft-fp/negsf2.c: Likewise. * soft-fp/negtf2.c: Likewise. * soft-fp/op-1.h: Likewise. * soft-fp/op-2.h: Likewise. * soft-fp/op-4.h: Likewise. * soft-fp/op-8.h: Likewise. * soft-fp/op-common.h: Likewise. * soft-fp/quad.h: Likewise. * soft-fp/single.h: Likewise. * soft-fp/soft-fp.h: Likewise. * soft-fp/subdf3.c: Likewise. * soft-fp/subsf3.c: Likewise. * soft-fp/subtf3.c: Likewise. * soft-fp/truncdfsf2.c: Likewise. * soft-fp/trunctfdf2.c: Likewise. * soft-fp/trunctfsf2.c: Likewise. * soft-fp/trunctfxf2.c: Likewise. * soft-fp/unorddf2.c: Likewise. * soft-fp/unordsf2.c: Likewise. * soft-fp/unordtf2.c: Likewise.
