Gheorghe-Teodor Bercea d5ae4e6501 [OpenMP][libomptarget] Enable the compilation of multiple bc libraries for runtime inlining 
Summary:
Different NVIDIA GPUs support different compute capabilities. To enable the inlining of runtime functions and the best performance on different generations of NVIDIA GPUs, a bc library for each compute capability needs to be compiled. The same compiler build will then be usable in conjunction with multiple generations of NVIDIA GPUs.
To differentiate between versions of the same bc lib, the output file name will contain the compute capability ID.
Depends on D14254

George Rokos 0dd6ed74fd [OpenMP] Initial implementation of OpenMP offloading library - libomptarget device RTLs. 
This patch implements the device runtime library whose interface is used in the code generation for OpenMP offloading devices.
Currently there is a single device RTL written in CUDA meant to CUDA enabled GPUs.
The interface is a variation of the kmpc interface that includes some extra calls to do thread and storage management that only make sense for a GPU target.

Joachim Protze e5e4afd6db [OMPT] Build runtime with OMPT support by default 
This patch enables OMPT by default if version 50 or later is built and the config says, that OMPT will be supported.

Jonas Hahnfeld 2e809acd0b Unify build documentation and convert to reStructuredText 
We now have several options that apply for both libraries and they
shouldn't be documented in multiple files. When already merging
the two Build_With_CMake.txt documents, convert them to
reStructuredText which is used for all of LLVM's documentation.
