Replace Sema::CheckVariableInitList, CheckConstantInitList, and CheckForCharArrayInitializer with CheckInitializerListTypes. The new routine now supports struct/union initializers.
...
This is a modified version of a patch by Eli Friedman. This version passes all of the clang tests and supports vectors:-)
Note that Eli and I are still unsatisfied the implementation of CheckInitializerListTypes(). We'd like to find a more elegant implementation. Nevertheless, this is a complex part of the standard (and may be hard to simplify). Since the complexity is localized to this routine, we can iterate without too much disruption:-)

Some minor restructuring around LValue and RValue types. The value "kind"
...
information is not separated into a "base" and "sub" type. Eventually the
value-tracking logic will know about LValues and RValues, but not about
specialized LValues and RValues; separating the "kind" information into bits
indicating whether an ExprValue is an LValue or an RValue from the bits that
specify the actual value type makes this separation easier.

Major "architectural" changes to the GRConstants analysis. We now reason about

abstract "L-values" and "R-values" when doing value tracking, and expanding
constant tracking to encompass tracking disjunctive sets of possible constants.
Further, the tree-walking is more efficient, as we don't blindly recurse the
tree if we won't generate new states.
