History
Joseph Myers 457663a7cd Add setpayloadsig, setpayloadsigf, setpayloadsigl. 
TS 18661-1 defines functions for manipulating the payloads of NaNs.
This patch implements the setpayloadsig functions for glibc; these are
like the setpayload functions, but produce a signaling NaN instead of
a quiet NaN.

The substance of the implementation was included with the setpayload
implementation, so the new files here just need to wrap the main files
with different defines to build the new functions.

Because the functions store a signaling NaN via a pointer and the
libm-test macros choose a suitable initial value for the variable in
such a case by comparing with the expected value, the relevant macro
needs to clear exceptions after FE_INVALID may have been raised by
that comparison.

Tested for x86_64, x86, mips64 and powerpc.

	* math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)]
	(setpayloadsig): New declaration.

	* math/Makefile (libm-calls): Add s_setpayloadsigF.
	* math/libm-test.inc (RUN_TEST_Ff_b1): Call feclearexcept
	(FE_ALL_EXCEPT) after initializing EXTRA_VAR.
	(setpayloadsig_test_data): New array.
	(setpayloadsig_test): New function.
	(main): Call setpayloadsig_test.
	* manual/arith.texi (FP Bit Twiddling): Document setpayloadsig,
	setpayloadsigf and setpayloadsigl.
