Content Cache only needs to be 4-byte aligned. Since it is stored in
an std::set, we can't make a strong guarantee about what its alignment
will be. Since I don't need the 3rd bit anyway yet, just change the
assertion.

Steve set me straight on this one. GCC was right, EDG was wrong: the
direct-initialization following a user-defined conversion can select
any constructor; it just can't employ any user-defined
conversions. So we ban those conversions and classify the constructor
call based on the relationship between the "from" and "to" types in
the conversion.

Split specific_decl_iterator, which had a run-time field for

Improve our handling of the second step in a user-defined conversion
sequence. Previously, we weren't permitting the second step to call
copy constructors, which left user-defined conversion sequences
surprisingly broken.
Now, we perform overload resolution among all of the constructors, but
only accept the result if it makes the conversion a standard
conversion. Note that this behavior is different from both GCC and EDG
(which don't agree with each other, either); I've submitted a core
issue on the matter.

Implement and test aggregate initialization in C++. Major changes:
- Support initialization of reference members; complain if any
reference members are left uninitialized.
- Use C++ copy-initialization for initializing each element (falls
back to constraint checking in C)
- Make sure we diagnose when one tries to provide an initializer
list for a non-aggregate.
- Don't complain about empty initializers in C++ (they are permitted)
- Unrelated but necessary: don't bother trying to convert the
decl-specifier-seq to a type when we're dealing with a C++
constructor, destructor, or conversion operator; it results in
spurious warnings.

Fix a couple bugs:
- NonLoc::MakeVal() would use sizeof(unsigned) (literally) instead of consulting
ASTContext for the size (in bits) of 'int'. While it worked, it was a
conflation of concepts and using ASTContext.IntTy is 100% correct.
- RegionStore::getSizeInElements() no longer assumes that a VarRegion has the
type "ConstantArray", and handles the case when uses use ordinary variables
as if they were arrays.
- Fixed ElementRegion::getRValueType() to just return the rvalue type of its
"array region" in the case the array didn't have ArrayType.
