David Sherwood 1d9775f684 [LV] Change VPLane::getAsRuntimeExpr to use constant 64-bit indices (#193206) ...

The canonical form preferred by instcombine is to use 64-bit values for
the index when it is a constant. We should try to do the same where
possible in the loop vectoriser as this reduces churn in the compiler.

It also makes other work easier, such as removing extra unnecessary
passes on the RUN line in the test directory which I plan to do
afterwards.
