Add -Wcpp-undef warning flagwip/erikd/cpp-undef
Summary:
When enabled, this new warning flag passes `-Wundef` to the C
pre-processor which causes the pre-processor to warn on uses of
the `#if` directive on undefined identifiers.
It is not currently enabled in any of the standard warning groups.
Test Plan:
Add a test to this commit and make sure the test passes
on all major platforms.
