[lit] Always quote arguments containing '[' on windows

Authored by mstorsjo on Tue, Apr 6, 3:38 AM.



This avoids breaking clang-tidy/infrastructure/validate-check-names.cpp
if 'not' is evaluated as a lit internal tool (making TestRunner
invoke 'grep' directly in that test, instead of invoking 'not', which
then invokes 'grep').

The quoting of arguments is still brittle if the executable is an
MSYS based tool though, as MSYS based tools incorrectly unescape
backslashes in quoted arguments (contrary to regular win32 argument
parsing rules), see D99406 and for more examples
of the issues.

Updated to include a testcase for the cases it fixes, and a clear example of an argument that this particular workaround still doesn't handle.

RUN lines that don't work as expected are often written as RUNX: to disable them. Maybe that's an old convention.
