[flang] Avoid cascading error in subscript triplet

If a bound of a subscript triplet is present but fails to analyze
due to an error, return nullopt rather than returning a Triplet with
that bound missing. This is so we can distinguish an absent bound from
an erroneous one and avoid spurious errors.

Unbundle KILL bundles in VirtRegRewriter

SplitKit forms invalid COPY subreg bundles without a leading
BUNDLE instruction. That manifests itself in post-RA scheduler
counting instruction and asserting on "Instruction count mismatch".

The bundle shall be undone by VirtRegRewriter::expandCopyBundle(),
but it does not because VirtRegRewriter::handleIdentityCopy() can
turn COPY bundle into a KILL bundle.

Process KILLs as well.
