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.

Erich Keane 9b26b17bc4 Fix double destruction of objects when OpenMP construct is canceled
When an omp for loop is canceled the constructed objects are being destructed 
twice.

It looks like the desired code is:

{

  Obj o;
  If (cancelled) branch-through-cleanups to cancel.exit.

}
[cleanups]
cancel.exit:

__kmpc_for_static_fini
br cancel.cont (*)

cancel.cont:

__kmpc_barrier
return

The problem seems to be the branch to cancel.cont is currently also going 
through the cleanups calling them again. This change just does a direct branch 
instead.
