asgerf@google.com b73bfcf636 dart2dart: Preserve variable names throughout the IR.
I had to add register allocation to avoid unsoundness in some cases where an expression needs to reference a previous version of a variable.

Register allocation is disabled for variables without an associated element, because it will typically block inlining of these variables.
