; REQUIRES: asserts
; Test that the register scavenger does not assert because a spill slot
; was not found. The bug is that the Hexagon spill code was not allocating
; the spill slot because the function that returns true, which indicates
; the code changed when a spill is inserted, was not always returning true.
