  [LV] Fix handling of interleaving linear args (#78725)

Currently when interleaving vector calls with linear arguments,
the Part is ignored and all vector calls use the initial value
from the first lane of the current iteration.

Fix this to extract from the correct part of the linear vector.

(cherry picked from commit d4c01714239e80d21e441c3886749fc56b743f81)
