This PR adds the necessary infrastructure to enable testing of the ACCImplicitData pass for FIR/HLFIR, along with comprehensive test coverage for implicit data clause generation in OpenACC constructs. New Infrastructure: - Add FIROpenACCSupport analysis providing FIR-specific implementations of OpenACCSupport interface methods for variable name extraction, recipe name generation, and NYI emission - Add FIROpenACCUtils with helper functions for: * Variable name extraction from FIR operations (getVariableName) * Recipe name generation with FIR type string representation * Bounds checking for constant array sections - Add ACCInitializeFIRAnalyses pass to pre-register FIR analyses (OpenACCSupport and AliasAnalysis) for use by subsequent OpenACC passes in the pipeline Refactoring in flang/lib/Lower/OpenACC.cpp: - Move bounds string generation and bounds checking to FIROpenACCUtils - Refactor recipe name generation to use fir::acc::getRecipeName Test Coverage: - acc-implicit-firstprivate.fir: Tests implicit firstprivate behavior for scalar types (i8, i16, i32, i64, f32, f64, logical, complex) in parallel/serial constructs with recipe generation verification - acc-implicit-data.fir: Tests implicit data clauses for scalars, arrays, derived types, and boxes in kernels/parallel/serial with default(none) and default(present) variations - acc-implicit-data-fortran.F90: Fortran tests verifying implicit data generation through bbc with both HLFIR and FIR - acc-implicit-data-derived-type-member.F90: Tests correct ordering of parent/child data clause operations for derived type members - acc-implicit-copy-reduction.fir: Tests enable-implicit-reduction-copy flag controlling whether reduction variables use copy or firstprivate This enables proper testing of implicit data clause generation through the flang optimizer pipeline for OpenACC directives.
