The motivation is that when starting a new backend, you often start with a minimal stub, pretty much just FooTargetMachine and FooTargetInfo. Once that's built, you might naturally try `llc -march=foo myinput.ll` and it seems more developer-friendly if this ends up asserting due to the lack of MCAsmInfo with an informative message rather than just segfaulting.

Revert "Add a test for clang-tidy using the clang-cl driver."

This reverts commit fd1908ce445eba4544d64cc68b3c03249e4bf614.

This should be the correct CL to revert.  The clang-side patch
that enabled this functionality was reverted, so this test needs
to be reverted until it gets fixed.

I'm having a bad day apparently.  I reverted the wrong CL.  This
puts it back.

The patch that made this test work needed to be reverted, so this
test needs to be reverted as well.
