[OpenMP] Sema and parsing for 'target parallel for simd' pragma

[kkwli0]

Summary

This patch is to implement sema and parsing for 'target parallel for simd' pragma.

I'm seeing a different set of diagnostics in two of these tests, because we default to C+11, which makes them fail for us. Ideally you'd conditionalize the tests on the value of __cplusplus (like Charles Li has been doing for a whole lot of the Clang tests). If that's inconvenient for you right now, would you mind if I added -std=c++03 to the following tests? It's just these two that need it:

target_parallel_for_simd_collapse_messages.cpp
target_parallel_for_simd_ordered_messages.cpp

[kkwli0]

I update the test cases in https://reviews.llvm.org/D22417.
