[Bug fortran/21375] New: Rising run-time errors at DEALLOCATE with STAT clause

["naf at naf dot net dot ru" <gcc-bugzilla at gcc dot gnu dot org>]

When errors happens in DEALLOCATE with STAT the run-time error rises instead
setting up STAT variable. For example, following code:

-----------------------------
PROGRAM MAIN
INTEGER, POINTER :: foo
INTEGER IERR
DEALLOCATE(foo,STAT=IERR)
WRITE (*,*) IERR
END PROGRAM
-----------------------------

fails with 'Fortran runtime error: Internal: Attempt to DEALLOCATE unallocated
memory.' instead of setting IERR.

This bug corresponds with #17792.
