Patch in progress

Here is a fix. The problem is that the original patch was 'leaking' temporary
registers, breaking things that rely on the fact that they can get sequential
ranges of temporaries. Here is a simple example:

function g(a, b) {
    return [a.toString(), b];

In addition to this fix, I will add assertions that assert the sequentiality of
sequential ranges of temporaries, and make tests for all node types that call
emitCall() or emitConstruct().
