  Log Message:
  -----------
  [flang][OpenMP] Check the context of the declare_simd directive (#209318)

OpenMP 6.0, 9.8 "declare_simd Directive", restricts the placement of the
directive:

  Any declare_simd directive must appear in the specification part of a
  subroutine subprogram, function subprogram, or interface body to which
  it applies.

Flang did not enforce this, and accepted the directive in the
specification part of a module, submodule, main program or block data.

Note: the restriction requiring the argument to name the procedure to
which the directive applies is not implemented here.

Fixes #205478
