Updates for the handling of Profile data in the JIT

Use the type weight_t instead of unsigned when dealing with BasicBlock weights.
Added new method getCalledCount to return the number of times that the method was called.
Added new method fgProfileRunsCount to return the number of scenario runs for the profile data.
Made the method fgIsUsingProfileWeight public instead of protected
Renamed fgCalledWeight to fgCalledCount
Updated the logic in getBBWeight and added comments explaining how it works.
