* clif-util: Make the `-t` flag work with the `wasm` subcommand
The presence of the flag was checked in the code, so it was essentially already
supported, but it was not properly configured when constructing
the CLI arguments parser.
* clif-util: also enable the `-c` flag for the `wasm` subcommand
Similar to the parent commit, this functionality is already supported, just a
mix up of the CLI parser construction made it not show up.
This commit introduces initial support for multi-value Wasm. Wasm blocks and
calls can now take and return an arbitrary number of values.
The encoding for multi-value blocks means that we need to keep the contents of
the "Types" section around when translating function bodies. To do this, we
introduce a `WasmTypesMap` type that maps the type indices to their parameters
and returns, construct it when parsing the "Types" section, and shepherd it
through a bunch of functions and methods when translating function bodies.
* Add ability to run CLIF IR using `clif-util run [-v] {file}` and add `test run` to cranelift-filetests to allow executing CLIF
This re-factors the compile/execute parts to a FunctionRunner that is shared between cranelift-filetests and clif-util. CLIF can be now be run using `clif-util run` as well as during `clif-util test` for files with a `test run` header. As before, only functions suffixed with a `run` comment are executed. The `run: fn(...) == ...` expression syntax is left for a subsequent change.
- Both the `wasm` and `compile` commands get this new subcommand, and it defaults to false. This means that test runs with `wasm` can request disassembly (the main reason I am doing this) while test runs with `compile` now must request it, this changes current behavior.
- Switch to using context.compile_and_emit directly, and make the reloc and trap printers just accumulate output, not print it. This allows us to factor the printing code into the disasm module.

Because of the way that the `pass` subcommand orders its arguments, the
positional "single-file" input cannot be optional with a default value, because
it is followed by required positional arguments. If it were optional, that would
result in argument ambiguity where `clap` cannot tell if the optional positional
argument is supplied, or if the given argument is the next required positional
argument.
