* Remove no-std code for cranelift_codegen::timings
no-std mode isn't supported by Cranelift anymore
* Simplify define_passes macro
* Add egraph opt timings
* Replace the add_to_current api with PassTimes::add
* Omit a couple of unused time measurements
* Reduce divergence between run and run_passes a bit
* Introduce a Profiler trait
This allows plugging in external profilers into the Cranelift profiling
framework.
* Add Pass::description method
* Remove duplicate usage of the compile pass timing
* Rustfmt
* cranelift-filetest: Add the ability to test `.wat` to assembly
* Make the load/store test case generator script use `.wat` tests
And generate tests that exercise both Wasm-to-CLIF lowering and Wasm all the way
to assembly.
* Remove old versions of generated load/store tests
* Add new generated load/store tests
* Fix filename reference in script
* clif-util: do not convert `anyhow::Error`s into strings into `anyhow::Error`s
* filetests: Use the debug formatting of `anyhow::Error`s
This provides the full error context, not just the source error's message.
