As discussed from RISC-V C-API PR #101 [1], As discussed in #96, current interface is insufficient to support some cases, like a vendor buying a CPU IP from the upstream vendor but using their own mvendorid and custom features from the upstream vendor. In this case, we might need to add these extensions for each downstream vendor many times. Thus, making __riscv_vendor_feature_bits guarded by mvendorid is not a good idea. So, drop __riscv_vendor_feature_bits for now, and we should have time to discuss a better solution.

Thanks. I've pushed this to the trunk. jeff
