Cranelift can be compiled with feature flags which can change its output. To
accomodate changes of output related to feature flags, test file can now include
`feature "..."` and `feature ! "..."` directives in the preamble of the test
file.
The test runner would skip the test if the flag does not match the expectation
of the test case.
* 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.
Major API-incompatible changes include:
- Introduce TrapCode::UnreachableCodeReached, used for unreachable in wasm.
- cranelift-wasm's `declare_signature` now takes its signature by value
- cranelift-wasm's `declare_table_elements` `elems` parameter now takes a boxed slice
- Remove cranelift-wasm's `ModuleEnvironment`'s `get_signature`,
`get_num_func_imports`, `get_func_type`, and `get_global`.
