compiler.cfg.linear-scan.allocation.state: fix #1345 by adding vreg to
...
the heap key
By having { start end vreg } as the key in the min-heap ordering is
guaranteed even if two intervals share the same start and end.

compiler.cfg.linear-scan.allocation.*: maybe a fix for #1227
...
The register allocator pops from the unhandled-intervals and
unhandled-sync-points heaps. If two live intervals share the same
start slot, then they can be popped in either order leading to
differently generated code. So instead use one
heap (unhandled-min-heap) and both the start and end slot as the heap
key to resolve tie-breakers
