Patch updates:

- Address review comments
- (u)int64_type is `long int` on RV64 rather than `long long int`
- Remove driver for bare metal RV32 target (to be posted in a subsequent patch and maybe discussed on cfe-dev).

>From my perspective, the only deficiency in this patch is now the tests (which I'll add to this review ASAP). Let me know if you see other remaining problems.
