add CMake option USE_STANDALONE_GBE_COMPILER and STANDALONE_GBE_COMPILER_DIR
At some platforms with old c/c++ environment, C++11 features are not
supported, it results in the failure to build the gbe compiler part
which depends on LLVM/clang using C++11 features.
The way to resolve is to build a standalone gbe compiler within another
feasible system, and build beignet with the already built standalone
gbe compiler by setting USE_STANDALONE_GBE_COMPILER=true. The path of
the standalone compiler is /usr/local/lib/beignet as default or could
be specified by STANDALONE_GBE_COMPILER_DIR.
Once USE_STANDALONE_GBE_COMPILER is given, all the gbe compiler relative
code will not be built any longer, only libcl.so and libgebinterp.so are
built. And libcl.so is special for GEN_PCI_ID, which is queried from the
building machie or could be specified as CMake option.
v2: separate the CMake option name.
update the commit comments.
add back the script for gen pci id, and build driver with it.
v3: add file FindStandaloneGbeCompiler.cmake to make the main cmakefile clean.
