amdflang: the deprecated - reduction identifier in task_reduction/in_reduction is rejected as not supported

! # Draft finding: omp52-clause-in_reduction-minus on afar
!
! - compiler: afar
! - toolchain: afar; arch: gfx942; machine: tuolumne; memory mode: unified; opt: -O2
! - program: catalog omp52-clause-in_reduction-minus (f90, version 52, sha256 685f776281adfd53)
! - expected: None (None; )
! - actual: rejected  (diagnostic: <tmpdir>/omp52-clause-in_reduction-minus.f90:31:19: error: The minus reduction operator is
!   deprecated since OpenMP 5.2 and is not supported in the REDUCTION clause.)
! - verdict: compiler_bug by rule R11-compile-rejection: a legal program the compiler rejects with a diagnostic (or whose link fails
!   on symbols the compiler's own code needs, or whose compile does not finish) while another compiler family compiles it
! - reason: 
! - citations: RUL-COMPILE-TIME (rulings.md)
! - legality: legal (legal by construction: offload.engine.gen / c_gen / acc_gen check every program against the catalog rules
!   and the
!   offload scope as it is built (no compiler))
! - witnesses: none
! - withdrawn: none

! spec (requirement): The minus operator is still a reduction identifier in OpenMP 5.2 (deprecated, not removed), so a
!   conforming compiler accepts it in reduction-type clauses.
! "following operators: +, - (deprecated), *, .and., .or., .eqv., .neqv." (5.2 §5.5.1 p.124 l.23)
! spec (requirement): The 5.2 list of changes states that the minus operator was deprecated, not removed.
! "The minus (-) operator for reductions was deprecated (see Section 5.5.5)." (5.2 §B.2 p.627 l.18)
! spec (requirement): The reduction identifier of task_reduction and in_reduction must match a previously declared
!   identifier of the same name and type; Table 5.2 lists - (deprecated) as implicitly declared for Fortran numeric
!   types.
! "The reduction identifier must match a previously declared reduction identifier of the same name and type for each
!   of the list items." (5.2 §5.5.5 p.131 l.4-5)
! spec (this program): task_reduction(-: s) and in_reduction(-: s) use the deprecated but valid minus identifier;
!   amdflang rejects it with a diagnostic that the minus reduction operator is not supported in the reduction clause.
