Remove common instructions from rv64 tests since they are now
covered by the rv64 run lines in the rv32 tests.
Add rv32-only* tests for a few cases that aren't common between
r32 and rv64.
Addresses review feedback from D95150.

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.
