Alexey Bataev 81c7ea0ec3 [OPENMP 4.0] Fixed codegen for 'cancellation point' construct.
Generate the next code for 'cancellation point':
if (__kmpc_cancellationpoint()) {
  __kmpc_cancel_barrier();
  <exit construct>;
}

Alexey Bataev d7589ffe1d [OPENMP] Fix codegen for ordered loop directives.
loops with ordered clause must be generated the same way as dynamic loops, but with static scheduleing.

Alexey Bataev db39021cee [OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492)
-fopenmp turns on OpenMP support and links libiomp5 as OpenMP library. Also there is -fopenmp={libiomp5|libgomp} option that allows to override effect of -fopenmp and link libgomp library (if -fopenmp=libgomp is specified).

Alexey Bataev 53223c986c [OPENMP] Generate !llvm.mem.loop_parallel_access metadata for loops with dynamic/guided scheduling.
Inner bodies of OpenMP worksharing loop-based constructs with dynamic or guided scheduling are allowed to be marked with !llvm.mem.parallel_loop_access metadata for better optimization. Worksharing constructs with static scheduling cannot be marked this way (according to OpenMP standard "A data dependence between the same logical iterations in two such loops is guaranteed").
Constructs with auto and runtime scheduling are also not marked because automatically chosen scheduling may be static also.

Alexey Bataev 98eb6e3d41 [OPENMP] Codegen for 'ordered' directive.
Add codegen for 'ordered' directive:

__kmpc_ordered(ident_t *, gtid);
<associated statement>;
__kmpc_end_ordered(ident_t *, gtid);
Also for 'for' directives with the dynamic scheduling and an 'ordered' clause added a call to '__kmpc_dispatch_fini_(4|8)[u]()' function after increment expression for loop control variable:

while(__kmpc_dispatch_next(&LB, &UB)) {
  idx = LB;
  while (idx <= UB) { BODY; ++idx;
    __kmpc_dispatch_fini_(4|8)[u](); // For ordered loops only.
  } // inner loop
}
