0eeb18f4d8 Improve the bytecode optimizer's ability to simplify `letrec's
to smaller `letrec' groups or even `let*'.
 The goal of the change is to avoid performance surprises
 when using internal definitions, especially when mixing
 experessions with definitions.
 It's a somewhat scary change. Besides the new transformation,
 the optimizer pass's coordinate system for `letrec' (and sometimes
 `let*') bindings changed.
 No standard benchmarks were harmed during the making of this
 optimization. (None were improved, either.)

7853d33349 Improved unboxed complex operations.
Intermediate results are kept as unboxed floats as long as we stay
within complex arithmetic code.

7921074eef Avoid boxing intermediate results when doing multiple complex
operations in a row.

However, because of values and let-values, we lose float unboxing.
If we have a single complex operation, this is much slower than my
previous implementation (though still faster than generic
operations). With 2 complex operations, the new implementation becomes
faster.
