work in progress

- Merged op_put_to_scope_with_profile and op_get_from_scope_with_profile into op_profile_types_with_high_fidelity by adding extra arguments to the opcode.
- Altered SymbolTable to use less memory by adding a rare data structure for type profiling.
- Created an interface to turn on and off type profiling.
- Refactored how I write to the log.
- deleted some unused code in HighFidelityLog.
- Implemented op_profile_types_with_high_fidelity in the baseline JIT by inlining the process of writing to the log and doing a small amount of type inference optimizations.

(This patch relies on https://bugs.webkit.org/show_bug.cgi?id=135358, therefore 135358 needs to land before this can land).
