On LLP64 Win64, 'states1' (for small version) was expanded to 'char *' for large version. Thus small version would be mischosen when nstates > 32 regardless of sizeof(long) on Win64.

IntervalMaps.

The IntervalMaps can have different template parameters, but the KeyT and Traits
types must be the same.

Tests are forthcoming.

It may be a bug that these opcodes are getting this far into machine code
generation.

live range splitting around loops guided by register pressure.

So far, trySplit() simply prints a lot of debug output.

A MachineLoopRange contains the intervals of slot indexes covered by the blocks
in a loop. This representation of the loop blocks is more efficient to compare
against interfering registers during register coalescing.

with some changes, and it might be useful in the future.

fold them down to intrinsics.  This currently only supports signed-addition, but could
be generalized if someone works out the magic constant formulas for other operations.
