This patchset should fix the bug#1701821 reported by Bruno Haible,
which makes the gnulib testsuite to fail for single precision libm
tests or for tests relying on unordered comparisons.
It also fixes an inversion of cause and flag bits in the FPSCR register,
which is unrelated with the reported bug. It also improves a bit the fneg
and fcmp instructions.
