-// This is a little utility pass that removes the gc.relocates inserted by
-// RewriteStatepointsForGC. Note that the generated IR is incorrect,
-// but this is useful as a single pass in itself, for analysis of IR, without
-// the GC.relocates. The statepoint and gc.result instrinsics would still be
-// present.
