Alexey Bataev 8c5555c39a [OPENMP][NVPTX]Mark more functions as always_inline for better 
performance.

Internally generated functions must be marked as always_inlines in most
cases. Patch marks some extra reduction function + outlined parallel
functions as always_inline for better performance, but only if the
optimization is requested.

target [teams distribute] simd costructs do not require full runtime for
the correct execution, we can run them without full runtime.

Alexey Bataev dc9e7dcbb0 [OPENMP][NVPTX]Run combined constructs with if clause in SPMD mode. 
All target-parallel-based constructs can be run in SPMD mode from now
on. Even if num_threads clauses or if clauses are used, such constructs
can be executed in SPMD mode.
