This patch fixes the ARM64 ABI for libm. fenv_t is now split in 32bit status
and 32bit control. This mirrors the AArch64 FPU control and status
registers (FPCR, FPSR).

The patch also refactors the libm implementation for ARM64 into a finer
grained control over the FPU registers.

Bionic-benchmarks has been expanded with 3 more benchmarks for floating
point operations. The new libm implementation for ARM64 performs better
over all the math benchmarks available.

Factored out common declarations to include/fenv.h and pushed
the implementation to .c files.
