[LLVMdev] darwin llvm-gfortran Polyhedron 2005 results

[Jack Howarth]

  Building the current release 2.7 branch on x86_64-apple-darwin10
with r81455 reverted, I get the following Polyhedron 2005 benchmark
results (with no test failures)...

This compares to the last time I ran these for the release 2.5 branch...

In general, since the 2.5 release, the code performance is better
but the compile time is somewhat regressed.
