- Tweak cross-class coalescing to be more aggressive when the target class is small. · 52375e6a
  Jakob Stoklund Olesen authored May 17, 2011
```
The greedy register allocator has live range splitting and register class
inflation, so it can actually fully undo this join, including restoring the
original register classes.

We still don't want to do this for long live ranges, mostly because of the high
register pressure of there are many constrained live ranges overlapping.

- Teach LiveInterval::isZeroLength about null SlotIndexes. · 4edf17d9
  Jakob Stoklund Olesen authored May 16, 2011
```
When instructions are deleted, they leave tombstone SlotIndex entries.
The isZeroLength method should ignore these null indexes.

This causes RABasic to sometimes spill a callee-saved register in the
abi-isel.ll test, so don't run that test with -regalloc=basic.  Prioritizing
register allocation according to spill weight can cause more registers to be
used.
