Pass the error string directly to llvm_unreachable instead of the residual
...
(0 && "error"). Rough consensus seems to be that g++ *should* be diagnosing
this because the pointer makes it not an ICE in c++03. Everyone agrees that
the current standard is silly and null-pointer-ness should not be based on
ICE-ness. Excellent fight scene in Act II, denouement weak, two stars.

explicit to trap bugs early.

Fix DenseMap iterator constness.
...
This patch forbids implicit conversion of DenseMap::const_iterator to
DenseMap::iterator which was possible because DenseMapIterator inherited
(publicly) from DenseMapConstIterator. Conversion the other way around is now
allowed as one may expect.
The template DenseMapConstIterator is removed and the template parameter
IsConst which specifies whether the iterator is constant is added to
DenseMapIterator.
Actually IsConst parameter is not necessary since the constness can be
determined from KeyT but this is not relevant to the fix and can be addressed
later.
