Alexey Bataev 68d230359a [OPENMP] Support for -fopenmp-simd option with compilation of simd loops
only.

Added support for -fopenmp-simd option that allows compilation of
simd-based constructs without emission of OpenMP runtime calls.

Alexey Bataev 98456c30ff [OPENMP] Fix DSA processing for member declaration.
If the member declaration is captured in the OMPCapturedExprDecl, we may
loose data-sharing attribute info for this declaration. Patch fixes this
bug.

Alexey Bataev fcfdcb4598 [OPENMP 4.0] Use 'declare reduction' constructs in 'reduction' clauses.
OpenMP 4.0 allows to define custom reduction operations using '#pragma
omp declare reduction' construct. Patch allows to use this custom
defined reduction operations in 'reduction' clauses.

Alexey Bataev 4b96eb8f82 [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).

Alexey Bataev 680e545622 [OPENMP] Fix for checking of data-sharing attributes for canonical var decls only.
Currently checks for active data-sharing attributes for variables are performed for found var decls. Instead these checks must be performed for canonical decls of these variables to avoid possible troubles with with the differently qualified re-declarations of the same variable, for example:
namespace A { int x; }
namespace B { using A::x; }
Both A::x and B::x actually reference the same object A::x and this fact must be taken into account during data-sharing attributes analysis.

Alexey Bataev ec17a34f77 [OPENMP] Codegen for 'reduction' clause in 'parallel' directive.
Emit a code for reduction clause. Next code should be emitted for reductions:

static kmp_critical_name lock = { 0 };

void reduce_func(void *lhs[<n>], void *rhs[<n>]) {
  ...
  *(Type<i> *)lhs[i] = RedOp<i>(*(Type<i> *)lhs[i], *(Type<i> *)rhs[i]);
  ...
}

... void *RedList[<n>] = {&<RHSExprs>[0], ..., &<RHSExprs>[<n> - 1]};
switch (__kmpc_reduce{_nowait}(<loc>, <gtid>, <n>, sizeof(RedList), RedList, reduce_func, &<lock>)) {
case 1:
  ...
  <LHSExprs>[i] = RedOp<i>(*<LHSExprs>[i], *<RHSExprs>[i]);
  ...
  __kmpc_end_reduce{_nowait}(<loc>, <gtid>, &<lock>);
  break;
case 2:
  ...
  Atomic(<LHSExprs>[i] = RedOp<i>(*<LHSExprs>[i], *<RHSExprs>[i]));
  ...
  break;
default:
  ;
}
Reduction variables are a kind of a private variables, they have private copies, but initial values are chosen in accordance with the reduction operation.
