 - This is a pretty slow / memory intensive implementation, and I will likely
   change it to an iterative model, but it works.

Fix two more diagnostic-on-stderr instances that thought they could hide from me -- they thought wrong.

Fix CompilerInstance::createOutputFile to use proper diagnostics, and (try to) update all clients to be able to handle failure.

Add value invalidation logic for block-captured variables.  Conceptually invoking a block (without specific reasoning of what the block does) can invalidate any value to it by reference when the block was created.

Make BlockDataRegion::referenced_vars_iterator an actual class that enforces that all MemRegions iterated over are VarRegions.

Don't pull vector sext through both hands of a logical operation, since doing so prevents the fusion of vector sext and setcc into vsetcc.
Add a testcase for the above transformation.
Fix a bogus use of APInt noticed while tracking this down.

both source operands.  In the canonical form, the 2nd operand is changed to an
undef and the shuffle mask is adjusted to only reference elements from the 1st
operand.  Radar 7434842.

overloaded-operator resolution is wildly untested, but the parallel code for
methods seems to satisfy some trivial tests.

Also change some overload-resolution APIs to take a type instead of an expression,
which lets us avoid creating a spurious CXXThisExpr when resolving implicit
member accesses.
