Allocating Registers
--------------------
The following table has one or more rows for each RefPosition that is handled during allocation.
The first column provides the basic information about the RefPosition, with its type (e.g. Def,
Use, Fixd) followed by a '*' if it is a last use, and a 'D' if it is delayRegFree, and then the
action taken during allocation (e.g. Alloc a new register, or Keep an existing one).
The subsequent columns show the Interval occupying each register, if any, followed by 'a' if it is
active, a 'p' if it is a large vector that has been partially spilled, and 'i'if it is inactive.
Columns are only printed up to the last modifed register, which may increase during allocation,
in which case additional columns will appear.
Registers which are not marked modified have ---- in their column.
