[PATCH] Add support for nowait and depend clauses in target construct in 4.1

[Jonathan Peyton]

Hi hfinkel,

The patch enables OpenMP 4.1 macros and build (build.pl and CMake).  It creates a new kind of tasks named proxy tasks which are not executed by OpenMP threads but OpenMP still needs to maintain its synchronization in between them and with other OpenMP tasks.  The most dramatic changes relate to the fact that the RTL had some assumptions about serialization and tasking that are no longer true.  tskm_immediate_exec is not supported by this patch.  4.1 headers were added, which are just copies of the 4.0 headers, but that is a large portion of this change.
