Allow |CRYPTO_is_NEON_capable| to be known at compile time, if possible.

If -mfpu=neon is passed then we don't need to worry about checking for
NEON support at run time. This change allows |CRYPTO_is_NEON_capable| to
statically return 1 in this case. This then allows the compiler to
discard generic code in several cases.
