The ARMLowOverheadLoops pass recalculated VPT block masks when it converts VCMP's inside VPT blocks into VPT's. The function to do so doesn't seem to handle debug info though, leading to invalid block creation or asserts at compile time.  Make sure the function skips any debug info between the MVE instructions it inspects.
