  Changed paths:

    M flang/test/Lower/OpenMP/declare-variant-construct.f90

  Log Message:
  -----------
  Preserve SIMD context for variant selection

SIMD selectors cannot match when lowering omits the enclosing SIMD trait.
Collect it so calls inside SIMD and DO SIMD select the correct variant.

  Log Message:
  -----------
  Preserve reachable metadirective variants across ranking and scopes

Incorrect candidate scores and stale scope boundaries can suppress required
loop diagnostics or let directives associate with loops outside their region.

Keep pending scopes consistent as directives are consumed, and preserve
candidate scores and highest-valued ordered matches when selecting and
merging reachable paths. Handle unknown properties without aborting ranking.

  Log Message:
  -----------
  Respect target boundaries during OpenMP variant lowering

Stop collecting construct traits at the innermost TARGET so lowering
agrees with semantic analysis when selecting metadirective replacements
and DECLARE VARIANT callees.
