[clang-lit] Added the run_long_tests param option/long_tests feature to toggle execut...

This will allow for longer running FileCheck based tests to be committed to
clang for use on buildbots, preventing the normal make-check cycle from
increasing in time significantly.

This is a necessary change in order to commit the end-to-end arm neon intrinsic
tests since FileCheck takes ~20 seconds to run said test due to the large amount
of neon intrinsics.

To force a test to run only when --param run_long_tests=true is passed in use
the following requires statement:

// REQUIRES: long_tests
