Subject: [PATCH] Add nextup and nextdown math functions
TS 18661 adds nextup and nextdown functions alongside nextafter to provide
support for float128 equivalent to it. This patch adds nextupl, nextup,
nextupf, nextdownl, nextdown and nextdownf to libm before float128 support.
nextup functions return the next representable value in the direction of
positive infinity and nextdown functions return the next representable value in
the direction of negative infinity. These are currently enabled as a GNU
extension.
