Running make check-stage2-std shows this warning:

compile_and_link: x86_64-unknown-linux-gnu/test/stdtest.stage2-x86_64-unknown-linux-gnu
/home/brian/dev/rust/src/libstd/rope.rs:1293:16: 1293:19 warning: unused variable: `pos`
/home/brian/dev/rust/src/libstd/rope.rs:1293         let mut pos     = 0u;

but pos is used in the following loop.

Add new options to compiletest (rust-lang#2605)

Add a few more options to compiletest which I'm planning to use on our benchmarks. rust-lang#2442 
  - "--report-time": Will report how long it took to run a test. This includes the time taken to process the expected file.
  - "--kani-flag": Allow us to pass extra arguments to all tests.
