Alex Richardson 34cc08e336 Save all fpcr/fpsr bits in the AArch64 fenv_t ... The existing code masked off all bits that it didn't know about. To be future-proof, we should save and restore the entire fpcr/fpsr registers. Additionally, the existing fesetenv() was incorrectly setting the rounding mode in fpsr instead of fpcr. This patch stores fpcr in the high 32 bits of fenv_t and fpsr in the low bits instead of trying to interleave them in a single 32-bit field. Technically, this is an ABI break if you re-compile parts of your code or pass a fenv_t between DSOs that were compiled with different versions of fenv.h. However, I believe we should fix this since the existing code was broken and passing fenv_t across DSOs should rarely happen.
