  1. [CodeExtractor] Allow to use 0 addr space for aggregate arg 

    The user of CodeExtractor should be able to specify that
the aggregate argument should be passed as a pointer in zero address
space.

CodeExtractor is used to generate outlined functions required by OpenMP
runtime. The arguments of the outlined functions for OpenMP GPU code
are in 0 address space. 0 address space does not need to be the default
address space for GPU device. That's why there is a need to allow
the user of CodeExtractor to specify, that the allocated aggregate param
is passed as pointer in zero address space.

  2. [OpenMP][OMPIRBuilder] Add support to omp target parallel 

    Added support for LLVM IR code generation which is used for handling
omp target parallel code. The call for __kmpc_parallel_51 is generated
and the parallel region is outlined to separate function.

The proper setup of kmpc_target_init mode is not included in the commit.
It is assumed that the SPMD mode for target init is properly set by other
codegen functions.

  4. Do not build the new Device RTL functions which cannot be compiled 

    Proposed implementation of the new device OpenMP functions relies on
internal functions which are not used in current version of the OpenMP
runtime.
