This adds support for collecting run-time profiling data with -Cprofile-generate which can be used to perform profile-guided optimization.
The API for retrieving the coverage data has also changed: there is now a single function capture_coverage which takes a sink into which the data is written. The sink must implement CoverageWriter, an implementation for Vec<u8> is provided if the alloc feature is enabled.
cc @xd009642 since this changes the API for no-alloc.
