Add setpayload, setpayloadf, setpayloadl [committed]

- Subject: Add setpayload, setpayloadf, setpayloadl [committed]
- Authentication-results: sourceware.org; auth=none
TS 18661-1 defines functions for manipulating the payloads of NaNs.
This patch implements the setpayload functions for glibc; these set a
number (pointed to by a function argument) to a quiet NaN with the
given payload, or to +0 if the given payload is not valid. The
implementations are structured to allow the substance of the
implementation to be shared with the setpayloadsig functions when
those are added.
The semantics in the TS are not entirely clear in the case where the
payload passed to the function is zero (see discussion on the WG14
reflector last month). This patch implements what seems the most
sensible interpretation, that -0 is never valid to give as the
payload, but +0 is valid in the case where the kind of NaN being
generated has its high mantissa bit set so payload 0 is actually
possible in such a NaN.
Tested for x86_64, x86, mips64 and powerpc. Committed.
