0001-fortran-Diagnose-allocatable-PROCEDURE-results-early.patch

Supersedes attachment 64075. This version uses gfc_check_conflict before
add_hidden_procptr_result and carries the required Assisted-by attribution.
The valid pointer form remains accepted and the allocatable form gets the
PROCEDURE/ALLOCATABLE conflict diagnostic. check-fortran and the libgomp
Fortran suites are clean.
