Ross McIlroy 8ff0ca1b1c [Compiler] Simplify UnoptimizedCompileJob
Simplifies the unoptimized compile job to have only three steps, the
on-main-thread prepare step, the off-thread compile step and the
on-main-thread finalization step.

As part of this change, the compiler dispatcher no longer supports
functions with outer scopeinfo's, since these need to be analysed on the
main thread.
