Jay Foad 0bd4365445 [LiveIntervals] Fix verification of early-clobbered segments ...

Enable verification of live intervals immediately after computing them
(when -early-live-intervals is used) and fix a problem that that
provokes: currently the verifier insists that a segment that ends at an
early-clobber slot must be followed by another segment starting at the
same slot. But before TwoAddressInstruction runs, the equivalent
condition is: a segment that ends at an early-clobber slot must have its
last use tied to an early-clobber def. That condition is harder to check
here, so for now just disable this check until tied operands have been
rewritten.
