[OpenMP] Support for the if-clause on the combined directive 'target parallel'. The if-clause on the combined directive potentially applies to both the 'target' and the 'parallel' regions. Codegen'ing the if-clause on the combined directive requires additional support because the expression in the clause must be captured by the 'target' capture statement but not the 'parallel' capture statement. Note that this situation arises for other clauses such as num_threads. The OMPIfClause class inherits OMPClauseWithPreInit to support capturing of expressions in the clause. A member CaptureRegion is added to OMPClauseWithPreInit to indicate which captured statement (in this case 'target' but not 'parallel') captures these expressions. To ensure correct codegen of captured expressions in the presence of combined 'target' directives, OMPParallelScope was added to 'parallel' codegen.

[OPENMP] Create non-const ident_t objects.

[OpenMP] Support for the if-clause on the combined directive 'target parallel'. The if-clause on the combined directive potentially applies to both the 'target' and the 'parallel' regions. Codegen'ing the if-clause on the combined directive requires additional support because the expression in the clause must be captured by the 'target' capture statement but not the 'parallel' capture statement. Note that this situation arises for other clauses such as num_threads. The OMPIfClause class inherits OMPClauseWithPreInit to support capturing of expressions in the clause. A member CaptureRegion is added to OMPClauseWithPreInit to indicate which captured statement (in this case 'target' but not 'parallel') captures these expressions. To ensure correct codegen of captured expressions in the presence of combined 'target' directives, OMPParallelScope was added to 'parallel' codegen.

// CHECK: call {{.*}}void (%struct.ident_t*, i32, void (i32*, i32*, ...)*, ...) @__kmpc_fork_call(%struct.ident_t* [[DEF_LOC]], i32 0, void (i32*, i32*, ...)* bitcast (void (i32*, i32*)* [[OMP_OUTLINED2:@.+]] to void (i32*, i32*, ...)*))
[OpenMP] Support for the if-clause on the combined directive 'target parallel'. The if-clause on the combined directive potentially applies to both the 'target' and the 'parallel' regions. Codegen'ing the if-clause on the combined directive requires additional support because the expression in the clause must be captured by the 'target' capture statement but not the 'parallel' capture statement. Note that this situation arises for other clauses such as num_threads. The OMPIfClause class inherits OMPClauseWithPreInit to support capturing of expressions in the clause. A member CaptureRegion is added to OMPClauseWithPreInit to indicate which captured statement (in this case 'target' but not 'parallel') captures these expressions. To ensure correct codegen of captured expressions in the presence of combined 'target' directives, OMPParallelScope was added to 'parallel' codegen.
