669e15e139 [ir] Add EmitBinary
This CL adds the machinery to emit binary operations to the IR. The
debug helper is split into Debug and Disassembler. The Disassembler is
used to help test the IR output.

e02377c2b3 [ir] Testing updates.
This CL renames the `Build` method in the test helper to be
`CreateBuilder` to maek the intention clearer. A second,
`CreateEmptyBuilder` is provided to allow for easier testing of
expressions.

The `current_flow_block` and `builder` are moved to public so they can
be used/updated during testing.

eee8d88210 Start adding IR.
This CL starts adding the basics for an IR for Tint. The IR is
a lower level representation then the AST with several of the
restrictions removed. For example, the IR is mutable, is a DAG
instead of a tree, and removes a number of WGSL constructs to
simplify transforms.
