Fixing bug #4608: Anomaly "output_value: abstract value (outside heap)".
The ARGUMENT EXTEND statement was wrongly using a CompatLoc instead of a Loc,
and this was not detected by typing "thanks" to the Gram.action magic. When
using CAMLP4, this was wreaking havoc at runtime, but not when using CAMLP5,
as the locations where sharing the same representation.
