a147a1da5c AArch64: libm: Fix ARM64 fenv_t and refactor ARM64 libm implementation.
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.

2d367905a2 Moved to a more openbsd-like fenv.h
Factored out common declarations to include/fenv.h and pushed
the implementation to .c files.

d1973ca513 bionic: rename aarch64 target to arm64
Rename aarch64 build targets to arm64.  The gcc toolchain is still
aarch64.
