Subject: [PATCH 2/2] ARM: Improve fenv implementation

Hi,

The second patch improves the fenv implementation by using the inline functions from fenv_private
where possible rather than duplicating functionality. The remaining functions are optimized in a
similar way to avoid unnecessary FPSCR writes (but no longer use __glibc_unlikely like in the
previous version).

OK for commit?
