[LV] Fix handling of interleaving linear args (#78725)
Browse files Browse the repository at this point in the history 
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.
