[Openmp-dev] Pushing four recent patches

[Peyton, Jonathan L]

I would like to push these four patches.  Ample opportunity for review has been given.

1) cmake_get_arch_v2.patch - Returns the architecture by probing predefined compiler macros.
2) aarch64_port_v4.patch - aarch64 port sent by C. Bergström.
3) hier_barrier_fix.patch - This small patch has a couple small fixes to the hierarchical barrier, predominately used on the Intel® MIC Architecture, in the context of teams and infinite blocktime.  The value of 0 for nesting level is used in the parallel region that consists of the team masters, and hierarchical barrier did not take that into consideration.
4) balanced_affinity.patch - This patch enables the use of KMP_AFFINITY=balanced on non-MIC Architectures.  The restriction for using balanced affinity on non-MIC architectures is it only works for one-package machines. It removes the KMP_MIC macro around balanced affinity code.

To apply patches:
$ patch -p0 < cmake_get_arch_v2.patch
$ patch -p1 < aarch64_port_v4.patch
$ patch -p0 < hier_barrier_fix.patch
$ patch -p0 < balanced_affinity.patch

* aarch64_port_v4.patch is built off of cmake_get_arch_v2.patch.
