Allow using external builds of the compiler-rt profile lib This changes the bootstrap config `target.*.profiler` from a plain bool to also allow a string, which will be used as a path to the pre-built profiling runtime for that target. Then `profiler_builtins/build.rs` reads that in a `LLVM_PROFILER_RT_LIB` environment variable. |
