Introduce -c source_file -o output_file build variables

Prior to this cl CompileCommandLine would (almost) unconditionally emit -c and
-o flags. This cl removes this logic and relies on crosstool to emit these
flags. This is another small step towards platform independent C++ rules.

Memory use is not affected, since the build variables used by this cl are already
exposed, this cl just forces crosstools to use it.

RELNOTES: None.
