CR3 is faster than 5.4 when not dealing with cascaded validation.

CR3 is significantly slower for cascading than 5.4 due to one call to
TypeVariableBindings executed at runtime.

When I say significantly, it's 2 time slower in the CascadedValidation test
of our performance tests, which is the worst case (e.g. the validation is
really fast as you only have a very simple constraint to apply).

The first 6 commits of the PR (the ones referencing HV-1438
are about this issue (e.g. have a list of compatible value extractors and
avoid playing with the type arguments at runtime).
