e7a5517a58 [OPENMP] Codegen for 'firstprivate' clause. 
This patch generates some helper variables that used as private copies of the corresponding original variables inside an OpenMP 'parallel' directive. These generated variables are initialized by copy using values of the original variables (with the copy constructor, if any). For arrays, initializator is generated for single element and in the codegen procedure this initial value is automatically propagated between all elements of the private copy.
In outlined function, references to original variables are replaced by the references to these private helper variables. At the end of the initialization of the private variables an implicit barier is generated by calling __kmpc_barrier(...) runtime function to be sure that all threads were initialized using original values of the variables.

9804fa5d48 Revert "[OPENMP] 'omp teams' directive basic support. Includes parsing and semantic analysis for 'omp teams' directive support from OpenMP 4.0. Adds additional analysis to 'omp target' directive with 'omp teams' directive." 
This reverts commit r219197 because it broke ARM self-hosting buildbots with
segmentation fault errors in many tests.

a5f070aec0 [OPENMP] Loop collapsing and codegen for 'omp simd' directive. 
This patch implements collapsing of the loops (in particular, in
presense of clause 'collapse'). It calculates number of iterations N
and expressions nesessary to calculate the nested loops counters
values based on new iteration variable (that goes from 0 to N-1)
in Sema. It also adds Codegen for 'omp simd', which uses
(and tests) this feature.

f8adcdc436 Track the difference between 
-- a constructor list initialization that unpacked an initializer list into
    constructor arguments and
 -- a list initialization that created as std::initializer_list and passed it
    as the first argument to a constructor

in the AST. Use this flag while instantiating templates to provide the right
semantics for the resulting initialization.

daff37013c AST: Mangle reference temporaries reliably 
Summary:
Previously, we would generate a single name for all reference
temporaries and allow LLVM to rename them for us.  Instead, number the
reference temporaries as we build them in Sema.
