Add control dependence analysis to opt (#4380)

Control dependence analysis constructs a control dependence graph,
representing the conditions for a block's execution relative to the
results of other blocks with conditional branches, etc.
This is an analysis pass that will be useful for the linter and
potentially also useful in opt. Currently it is unused except for the
added unit tests.
