This adds additional bit manipulation instructions to the RiscV 64 bit simulator.
It also factors out some of the encoding initializers so that they can be
reused across multiple decoders without having to replicate them.

This also fixes a decoding issue due to underspecified encodings of some vector memory instructions.
