[PATCH] tree-optimization/107956 - ICE with NULL call LHS

[rguenther--- via Gcc-patches]

The following adds a missing check for a NULL call LHS in the
vector pattern recognizer.

Pushed as obvious.

        PR tree-optimization/107956
        * tree-vect-patterns.cc (vect_recog_mask_conversion_pattern):
        Check for NULL LHS on masked loads.
