1fa3ddf018 Return RegInfo by value from TargetIsa::register_info(). 
The struct is just a pair of static references, and we don't need the
double indirection.

96e0a3273c Return slices of live-ins and arguments from ebb_top(). 
The coloring algorithm needs to process these two types of live values
differently, so we may as well provide the needed info.

2317142c75 Add a Layout::next_ebb() method. 
This lets us iterate over the blocks in a function without holding a
reference to the layout.

2c31041640 Live Value Tracker. 
Keep track of which values are live and dead as we move through the
instructions in an EBB.

5a1d9561a7 Coalesce live range intervals in adjacent EBBs 
LiveRanges represent the live-in range of a value as a sorted
list of intervals. Each interval starts at an EBB and continues
to an instruction. Before this commit, the LiveRange would store
an interval for each EBB. This commit changes the representation
such that intervals continuing from one EBB to another are coalesced
into one.

Fixes #37.

f6391c57e8 Compute register affinities during liveness analysis. 
Each live range has an affinity hint containing the preferred register
class (or stack slot). Compute the affinity by merging the constraints
of the def and all uses.

933dfc70c1 Fix a dead code warning from the new Rust compiler. 
On ISAs with no instruction predicates, just emit an unimplemented!()
stub for the check_instp() function. It is unlikely that a finished ISA
will not have any instruction predicates.

dab96d8ea2 Add entity lists. 
Like a vector, but with a tiny footprint, and allocated from a pool so
all memory can be released very quickly.

16f4b4c7d5 Implement value affinities for register allocation. 
An SSA value is usually biased towards a specific register class or a
stack slot, depending on the constraints of the instructions using it.

Represent this bias as an Affinity enum, and implement a merging
algorithm for updating an affinity to satisfy a new constraint.

Affinities will be computed as part of the liveness analysis. This is
not implemented yet.
