[OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492) -fopenmp turns on OpenMP support and links libiomp5 as OpenMP library. Also there is -fopenmp={libiomp5|libgomp} option that allows to override effect of -fopenmp and link libgomp library (if -fopenmp=libgomp is specified).

Account for calling convention specifiers in function definitions in IR test cases Several tests wouldn't pass when executed on an armv7a_pc_linux triple due to the non-default arm_aapcs calling convention produced on the function definitions in the IR output.

Support matching signext attribute in the parallel_num_threads_codegen test to appease clang-cmake-mips builder. The Mips target adds the signext attribute to signed 32-bit integers in order to support the N32/N64 correctly. Integers must be promoted to 64-bit bit on these ABI's. llvm-svn: 222618

[OPENMP 4.5] Codegen for member decls in 'lastprivate' clause. OpenMP 4.5 allows to privatize non-static member decls in non-static member functions. Patch captures such decls by reference in general (for bitfields, by value) and then operates with this capture. For bitfields, at the end of codegen for lastprivates original bitfield is updated with the value of captured copy. llvm-svn: 261824
