// This file implements a linear scan register allocator.
// This file implements an iterative scan register
// allocator. Iterative scan is a linear scan variant with the

//
// It performs linear scan and keeps a list of the registers it cannot
// allocate. It then spills all those registers and repeats the
// process until allocation succeeds.
