This reverts CL 207477, restoring CL 207352 with a fix for the regression observed in the Windows builders. cmd/compile evidently does not fully support NUL as an output on Windows, so this time we write ignored 'compile' outputs to temporary files (instead of os.DevNull as in CL 207352). Updates #28387 Fixes #35619 Change-Id: I2edc5727c3738fa1bccb4b74e50d114cf2a7fcff Reviewed-on: https://go-review.googlesource.com/c/go/+/207602 Run-TryBot: Bryan C.
