Revert "[analyzer] Support for naive cross translation unit analysis"

Also revert "[analyzer] Fix a compiler warning"
This reverts commits r326323 and r326324.

Reason: the commits introduced a cyclic dependency in the build graph.
This happens to work with cmake, but breaks out internal integrate.
