* Crude VM profiler

* Added --profileVM flag, refactoring

* fixed FileLine hash

* Use TLineInfo instead of own FileLine, updated formatting

* Refactoring, moved PStackFrame to vmdefs for cleaner data structure

* Moved vmprofiler to separate file

* Simplified TLineInfo hash, use toFileLineCol for output

* Hash

* Moved profile data into Config, dump only once at end of run

* Changed profile output header to show '#instr' instead of 'count'
