[OpenMP] Base support for target directive codegen on NVPTX device. Summary: This patch adds base support for codegen of the target directive on the NVPTX device. Reviewers: ABataev Differential Revision: http://reviews.llvm.org/D17877 Reworked test case after buildbot failure on windows. Updated patch to integrate r263837 and test case nvptx_target_firstprivate_codegen.cpp. llvm-svn: 264018

// Test target codegen - host bc file has to be created first.
[OpenMP] Use fopenmp prefix for all options introduced by the offloading implementation. Summary: This patch changes the options used by offloading to start with -fopenmp instead of -fomp. This makes the option naming more consistent and materializes a suggestion by Richard Smith in http://reviews.llvm.org/D9888.

[OpenMP] Codegen for the 'target parallel' directive on the NVPTX device. This patch adds codegen for the 'target parallel' directive on the NVPTX device. We term offload OpenMP directives such as 'target parallel' and 'target teams distribute parallel for' as SPMD constructs. SPMD constructs, in contrast to Generic ones like the plain 'target', can never contain a serial region. SPMD constructs can be handled more efficiently on the GPU and do not require the Warp Loop of the Generic codegen scheme. This patch adds SPMD codegen support for 'target parallel' on the NVPTX device and can be reused for other SPMD constructs.

[OPENMP] Allow value of thread local variables in target regions. If the variable is marked as TLS variable and target device does not support TLS, the error is emitted for the variable even if it is not used in target regions. Patch fixes this and allows to use the values of the TLS variables in target regions. llvm-svn: 303768

[OpenMP] Update target codegen for NVPTX device. This patch includes updates for codegen of the target region for the NVPTX device. It moves initializers from the compiler to the runtime and updates the worker loop to assume parallel work is retrieved from the runtime. A subsequent patch will update the codegen to retrieve the parallel work using calls to the runtime. It includes the removal of the inline attribute for the worker loop and disabling debug info in it. This allows codegen for a target directive and serial execution on the NVPTX device.
