Don't fail to remove files if they are missing In the backend we may want to remove certain temporary files, but in certain other situations these files might not be produced in the first place. We don't exactly care about that, and the intent is really that these files are gone after a certain point in the backend. Here we unify the backend file removing calls to use `ensure_removed` which will attempt to delete a file, but will not fail if it does not exist (anymore). The tradeoff to this approach is, of course, that we may miss instances were we are attempting to remove files at wrong paths due to some bug – compilation would silently succeed but the temporary files would remain there somewhere. 2021-02-14 10:27:08 -06:00			`// build-pass`
session: stabilize split debuginfo on linux Stabilize the `-Csplit-debuginfo` flag... - ...on Linux for all values of the flag. Split DWARF has been implemented for a few months, hasn't had any bug reports and has had some promising benchmarking for incremental debug build performance. - ..on other platforms for the default value. It doesn't make any sense that `-Csplit-debuginfo=packed` is unstable on Windows MSVC when that's the default behaviour, but keep the other values unstable.
