Extend BitsetType of TF's type system from 32 to 64 bit.
At the moment all 32 bits are used, so we can't add any new types.
This CL only adds support for > 32 types to C++. The bitset is also
mirrored in Torque. In the Torque definition, we just expose an
unstructured uint32 for the higher bits of the bitfield, because Toruqe
can't deal with 64 bit types on 32 bit platforms (yet) and we also can't
have multiple 1-bit bitfields within a single class (yet).
