[Openmp-dev] suppress more unused-variable and unused-function warnings

[Jack Howarth]

Jonathan,
      The attached patch eliminates most of the unused-variable and
unused-function warnings during the cmake build of openmp on
x86_64-apple-darwin14. The resulting build shows no regressions in the
OpenMP3.1_Validation test suite at -m64 or -m32.
                 Jack
ps The remaining instances fall in three main categories...

1) instances of "warning: unused variable 'temp_val'
[-Wunused-variable]" from runtime/src/kmp_atomic.c

2) instances of "warning: unused variable '__kmp_build_check_*'
[-Wunused-variable]" from runtime/src/kmp_itt.inl,
runtime/src/kmp_itt.c, runtime/src/kmp_global.c and
runtime/src/kmp_dispatch.cpp.

3) instances of "warning: unused function '__kmp_x86_pause'
[-Wunused-function]" from runtime/src/kmp.h
