<pre>If a block is defined in a function template, its instantiation will have a
null SignatureAsWritten. Looking at TreeTransform::TransformBlockExpr, it seems
that this is just an oversight, and that one ought to be able to transform the
BlockDecl's SignatureAsWritten.
This affects the analyzer in a few mild ways, and implies that the indexer
might miss a few uses of certain types. (Or perhaps not, since the enclosing
BlockExpr will have the correct type.)
