Previously, when generating template type-checking code, casts to 'any' were
produced as `expr as any`, regardless of the expression. However, for
certain expression types, this led to precedence issues with the cast. For
example, `a !== b` is a `ts.BinaryExpression`, and wrapping it directly in
the cast yields `a !== b as any`, which is semantically equivalent to
`a !== (b as any)`. This is obviously not what is intended.
Instead, this commit adds a list of expression types for which a "bare"
wrapping is permitted. For other expressions, parentheses are added to
ensure correct precedence: `(a !== b) as any`
