Tests and drivers updated, still need to shuffle dirs.

helper isConstantInitializer) to check whether an initializer is
constant. This passes tests, but it's possible that it'll cause
regressions with real-world code.
Future work:
1. The diagnostics obtained this way are lower quality at the moment;
some work both here and in Evaluate is needed for accurate diagnostics.
2. We probably need some extra code when we're in -pedantic mode so we
can strictly enforce the rules in C99 6.6p7.
3. Dead code cleanup (this should wait until after 2, because we might
want to re-use some of the code).

casting pointers to integers.
Eventually, we should check whether we can evaluate an expression
using Expr::tryEvaluate, and this codepath should be tightened to only
handle standard-compliant cases.
