Change subject: python: Add a --silent-redirect option to gem5.
......................................................................
python: Add a --silent-redirect option to gem5.
This complements the --redirect-stdout and --redirect-stderr options and
supresses the message about where those streams are being redirected
which print to the original stdout.
Usually this is very helpful since it lets you know where to look for
simulator output. If you're running gem5 in an automated environment
like our testing framework however, the file name is a random temp file
which will be deleted as soon as the test is finished running.
The --silent-redirect option can be used in these particular scenarios
to, for example, avoid lots and lots of useless lines in the test output
naming files that no longer exist.
