Joel E. Denny 7d5bc55433 [OpenMP] Permit map with DSA on combined directive
For `map`, the following restriction changed in OpenMP 5.0:

* OpenMP 4.5 [2.15.5.1, Restrictions]: "A list item cannot appear in
  both a map clause and a data-sharing attribute clause on the same
  construct.

* OpenMP 5.0 [2.19.7.1, Restrictions]: "A list item cannot appear in
  both a map clause and a data-sharing attribute clause on the same
  construct unless the construct is a combined construct."

This patch removes this restriction in the case of combined constructs
and OpenMP 5.0, and it updates Sema not to capture a scalar by copy in
the target region when `firstprivate` and `map` appear for that scalar
on a combined target construct.

This patch also adds a fixme to a test that now reveals that a
diagnostic about loop iteration variables is dropped in the case of
OpenMP 5.0.  That bug exists regardless of this patch's changes.

// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
