[OpenMP] Use the OpenMPIRBuilder for `omp parallel` This allows to use the OpenMPIRBuilder for parallel regions. Code was extracted from D61953 and adapted to work with the new version (D70109).

[OPENMP] Emit __kmpc_cancel_barrier() and code for 'cancellation point' only if 'cancel' is found. Patch improves codegen for OpenMP constructs. If the OpenMP region does not have internal 'cancel' construct, a call to 'void __kmpc_barrier()' runtime function is generated for all implicit/explicit barriers. If the region has inner 'cancel' directive, then ``` if (__kmpc_cancel_barrier()) exit from outer construct; ``` code is generated. Also, the code for 'canellation point' directive is not generated if parent directive does not have 'cancel' directive. llvm-svn: 247681

[OpenMP][OMPIRBuilder] Introducing the `OMPBuilderCBHelpers` helper class This patch introduces a new helper class `OMPBuilderCBHelpers`, which will contain all reusable C/C++ language specific function- alities required by the `OMPIRBuilder`. Initially, this helper class contains the body and finalization codegen functionalities implemented using callbacks which were moved here for reusability among the different directives implemented in the `OMPIRBuilder`, along with RAIIs for preserving state prior to emitting outlined and/or inlined OpenMP regions. In the future this helper class will also contain all the different call backs required by OpenMP clauses/variable privatization.

// IRBUILDER: [[EXIT2]]
[OpenMP][FIX] Collect blocks to be outlined after finalization Finalization can introduce new blocks we need to outline as well so it makes sense to identify the blocks that need to be outlined after finalization happened. There was also a minor unit test adjustment to account for the fact that we have a single outlined exit block now.
