[turbofan] Add support for eager/soft deoptimization reasons.

So far TurboFan wasn't adding the deoptimization reasons for eager/soft
deoptimization exits that can be used by either the DevTools profiler or
the --trace-deopt flag. This adds basic support for deopt reasons on
Deoptimize, DeoptimizeIf and DeoptimizeUnless nodes and threads through
the reasons to the code generation.

Also moves the DeoptReason to it's own file (to resolve include cycles)
and drops unused reasons.

Hey Jaro,

Please take a look.
