libomp: Update to latest; move installs into (include|lib)/libomp to facilitate clang modifications for -fopenmp. Add +top_level variant for users who want them in include/ and lib/ directly.

 notes "
-    Use with llvm-3.7/clang-3.7 (both built with 'assertions' variant DISABLED)
-    via:
-      -I${prefix}/include -L${prefix}/lib -fopenmp=libomp
+  Use with clang-3.\[78\] (when built with +openmp variant) by adding
+  \"-fopenmp\" to your compile and link lines.
+  (Or \"-I${prefix}/include/libomp -L${prefix}/lib/libomp -fopenmp\"
+  if clang is installed without +openmp.)
