[PATCH] Fix pr2570 test on OpenBSD

[Brad Smith]

The pr2570 test is failing on OpenBSD like so..

******************** TEST 'LLVM :: Transforms/LoopStrengthReduce/pr2570.ll' FAILED ********************
Script:
--
/buildbot-llvm/clang-openbsd/llvm/Release+Asserts/bin/opt < /buildbot-llvm/clang-openbsd/llvm/test/Transforms/LoopStrengthReduce/pr2570.ll -loop-reduce -S | grep "phi\>" | /buildbot-llvm/clang-openbsd/llvm/Release+Asserts/bin/count 8
--
Exit Code: 1

Command Output (stderr):
--
Expected 8 lines, got 0.


Because the use of grep is using a GNU grep extension. Attached is a patch to fix the use of
grep so it'll work with non-GNU implmentations.
