<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Refactor linear reg alloc to remember past assignments.

We used to pick the first free register, which

is damn fast but produces fixup blocks on the regular.

Now we look for past assignments first. This means for

loops with blocks A, B, C if a variable is live in A & C

we will pick the right register (if available) in C.

This avoids some needless fixup blocks.
