Avoid remat'ing instructions whose def have sub-register indices for now. It's just really really hard to get all the cases right.

ValueManager::makeArrayIndex()/convertArrayIndex() methods.  This
handles yet another crash case when reasoning about array indices of
different bitwidth and signedness.

means that two separate raw_ostreams are doing buffering before data is
sent to the underlying stream. Besides the inefficiency of redundant
buffering, the second level of buffering doesn't recieve flush()
requests.

Fix this by having formatted_raw_ostream set the underlying raw_ostream
to be unbuffered. This eliminates inefficiency due to redundant buffering,
and it makes the flush() disconnect harmless.

This fixes PR4559.

(1) Moved the SValuator object from GRExprEngine to ValueManager.  This
   allows ValueManager to use the SValuator when creating SVals.

(2) Added ValueManager::makeArrayIndex() and
    ValueManager::convertToArrayIndex(), two SVal creation methods
    that will help RegionStoreManager always have a consistent set of
    SVals with the same integer size and type when reasoning about
    array indices.

 - This isn't needed anymore, we require clients to call the appropriate

This extra check is not trigged when runnning "make check" on top-of-tree.

Change error message to better match llvm_unreachable() grammar.

Don't call llvm_unreachable() when writing error messages to a file, but keep going.
