Add __riscv_vector and __riscv_bitmanip for V and B extensions. #9

Closed jim-wilson closed 5 years ago

We have assembler ports for the V and B extensions, so we should be thinking about adding preprocessor macros for them. riscv_vector seems straightforward. __riscv_bitmanipulation seems inconveniently long, but riscv_bitmanip looks OK, and is consistent with the B extension gas/gcc patches. I asked in a riscv/riscv-bitmanip issue if they are OK with this. We should wait for comments in case they want to suggest something different.
