New Revision: 40988

URL: http://llvm.org/viewvc/llvm-project?rev=40988&view=rev
Log:
Add a test script for counting lines. This can be used instead of the
"| grep foo | wc -l | grep 2" idiom used by many tests, so that, for
example, tests don't mistakenly accept a count of 12 when 2 is
expected. Also, the new form is more consice: "| grep foo | count 2".
