Provide option for specifying the profiler runtime

Browse source 
Currently, if `-Zinstrument-coverage` is enabled, the target is linked
against the `library/profiler_builtins` crate (which pulls in LLVM's
compiler-rt runtime).

This option enables backends to specify an alternative runtime crate for
handling injected instrumentation calls.
