Lit's test suite has [tests where RUN lines containing true/false execute with lit's internal shell](https://github.com/llvm/llvm-project/blob/main/llvm/utils/lit/tests/Inputs/shtest-run-at-line/internal-shell/basic.txt) (not bash), and they [appear to succeed in windows bots](https://lab.llvm.org/buildbot/#/builders/216).  That suggests to me that true/false are available as external commands there.  Maybe @dyung can shed some light on that setup.

Is the goal of this patch to relax windows installation requirements, or am I just misunderstanding what's happening?
