Go back to comparing spill weights when deciding if interference can be evicted.
...
It gives better results. Sometimes, a live range can be large and still have
high spill weight. Such a range should not be spilled.

Renumber slot indexes locally when possible.
...
Initially, slot indexes are quad-spaced. There is room for inserting up to 3
new instructions between the original instructions.
When we run out of indexes between two instructions, renumber locally using
double-spaced indexes. The original quad-spacing means that we catch up quickly,
and we only have to renumber a handful of instructions to get a monotonic
sequence. This is much faster than renumbering the whole function as we did
before.

Number SlotIndexes uniformly without looking at the number of defs on each instruction.

You can't really predict how many indexes will be needed from the number of
defs, so let's keep it simple.
Also remove an extra empty index that was inserted after each basic block. It
was intended for live-out ranges, but it was never used that way.

Revert commit 126684 "Use the correct shift amount type". It is only the correct
...
type after type legalization has completed. Before then it may simply not be big
enough to hold the shift amount, particularly on x86 which uses a very small type
for shifts (this issue broke stuff in the past which is why LegalizeTypes carefully
uses a large type for shift amounts).

it. It's been assumed up til now that it would be in its immediate

Modify the code to more thoroughly check for an 'eh.selector' call in
successors. It only looks at a successor if we get there as a result of an
unconditional branch.
