Zachary Turner fb0dd311e1 [pdb] Change type visitor pattern to be dynamic.
This allows better catching of compiler errors since we can use
the override keyword to verify that methods are actually
overridden.

Also in this patch I've changed from storing a boolean Error
code everywhere to returning an llvm::Error, to propagate richer
error information up the call stack.
