Fix a bug in LSR's dead-PHI cleanup. If a PHI has a def-use chain that

leads into a cycle involving a different PHI, LSR got stuck running

track of visited PHIs and stop searching if we see one more than once.
This fixes PR2570.

Switch on the use of arbitrary precision integers in scalar evolution. This will

bail after 256-bits to avoid producing code that the backends can't handle.
Previously, we capped it at 64-bits, preferring to miscompile in those cases.
This change also reverts much of r52248 because the invariants the code was
expecting are now being met.
