This adds {{$}} to most of the CHECK lines for errors about what
extension an instruction requires. This ensures we check all the
extensions when there is a list.

Agreed policy is that RISC-V extensions that have not yet been ratified
should be marked as experimental, and enabling them requires the use of
the -menable-experimental-extensions flag when using clang alongside the
version number. These extensions have now been ratified, so this is no
longer necessary, and the target feature names can be renamed to no
longer be prefixed with "experimental-".

Add tests to make sure common instructions are accepted in RV64
and not just RV32.

It's not really clear in the spec that these are in Zbp now, but
that's what I've gather from previous commits to the spec. I've
file an issue to get it documented properly.

This adds the instruction encoding and mnenomics for the proposed
RISC-V Bit Manipulation extension (version 0.92). It is implemented with
each category of instruction as its own target feature, with the 'b'
extension feature enabling all options. Since this extension is not yet
ratified, all target features are prefixed with 'experimental-' to note
their status.
