v0.0.0-8100-gc857dada4

Control opt pipeline using toolchains.

Toolchains allow one to configure aspects of compilation in a reasonably straightforward way. This change makes a toolchain responsible for selecting the default pass pipeline used by XLS.

Note that this does not currently allow toolchains to control the actual tools used in compilation and the separate (confusingly named) xls_toolchain remains the only way to do that and is unchanged.

v0.0.0-8094-gd176e957f

Added 31 similar IR nodes to the IR Fuzzer.

I added more IR nodes, specifically IR ops similar to Add because we already have infrastructure to easily add these nodes. This required updating the proto, visitor, and IR node generator. A lot of testing and debugging was done to iron out test cases associated with different ops. This CL is large because most of the code dealing with Ops is repetative and configuring large protobuf tests.

[xls] Add `QueryEngine::Covers`

This makes it simpler to test whether a node can equal a concrete `Bits` value.
