aarch64: Bump AARCH64_APPROX_MODE to 64 bits
We now have more than 32 scalar and vector float modes, so the
32-bit AARCH64_APPROX_MODE would invoke UB for some of them.
Bumping to a 64-bit mask fixes that... for now.
Ideally we'd have a static assert to trap this, but logically
it would go at file scope. I think it would be better to wait
until the switch to C++11, so that we can use static_assert
directly.

gcc/
* config/aarch64/aarch64-protos.h (AARCH64_APPROX_MODE): Operate
on and produce uint64_ts rather than ints.
(AARCH64_APPROX_NONE, AARCH64_APPROX_ALL): Change to uint64_ts.
(cpu_approx_modes): Change the fields from unsigned int to uint64_t.
