, or ref mut x
?

If an explicit type was provided for this variable binding, this holds the source Span of that type.
NOTE: If you want to change this to a HirId
, be wary that
doing so breaks incremental compilation (as of this writing),
while a Span
does not cause our tests to fail.

Place of the RHS of the =, or the subject of the match
where this
variable is initialized. None in the case of let PATTERN;
.
Some((None, ..)) in the case of and let [mut] x = ...
because
(a) the right-hand side isn't evaluated as a place expression.
(b) it gives a way to separate this case from the remaining cases
for diagnostics.
