Enable pattern initialization in test builds

Clang recently added a new flag which will initialize variables with an
intentionally invalid (or likely to be invalid) pattern to catch
accidental assumptions about the initial contents of a variable.

This change enables that flag in test builds, and when combined with
UBSan should help detect these conditions should they arise.
