Add support for FreeBSD
Port the OpenMP runtime to FreeBSD along with associated build system changes. Also begin to generalize affinity capabilities so they aren't tied explicitly to Windows and Linux. The port builds with stock clang and gmake and has no additional runtime dependencies. All but a handful of the validation suite tests are now passing on FreeBSD 10 x86_64. llvm-svn: 202478
