This is a reland of 435b482638
inlineStatement now takes a `const Expression* resultExpr` instead of
`const Expression& resultExpr` because resultExpr will be null for a
void function.
Original change's description:
> Support out parameters that use a swizzle.
>
> This CL also removes the `VariableExpression` class that was briefly
> added in a prior CL. This class was intended to support cloning an
> expression while changing the refKind of a VariableReference inside of
> the expression, but it added state and complexity. In this CL, rather
> than track this via extra state, the inliner just recurses into the
> expression as needed to find its VariableReference. Since most relevant
> expressions are just a VariableReference anyway, this is inexpensive.
