Optimizing: Add direct calls to math intrinsics

Support the double forms of:
  cos, sin, acos, asin, atan, atan2, cbrt, cosh, exp, expm1,
  hypot, log, log10, nextAfter, sinh, tan, tanh

Add these entries to the vector addressed off the thread pointer. Call
the libc routines directly, which means that we have to implement the
native ABI, not the ART one. For x86_64, that includes saving XMM12-15
as the native ABI considers them caller-save, while the ART ABI
considers them callee-save.  We save them by marking them as used by the
call to the math function.  For x86, this is not an issue, as all the XMM
registers are caller-save.

Other architectures will call Java as before until they are ready to
implement the new intrinsics.

Bump the OAT version since we are incompatible with old boot.oat files.
