Fixed calculation of penalty when breaking tokens.

Summary:
Introduced two new style parameters: PenaltyBreakComment and
PenaltyBreakString. Add penalty for each character of a breakable token beyond
the column limit (this relates mainly to comments, as they are broken only on
whitespace). Tuned PenaltyBreakComment to prefer comment breaking over breaking
inside most binary expressions.
Fixed a bug that prevented *, & and && from being considered TT_BinaryOperator
in the presense of adjacent comments.

Re-commit r183466 with a fix to make the TypeLoc casting machinery work
correctly in the presence of qualified types.

(I had to change the unittest because it was trying to cast a
QualifiedTypeLoc to TemplateSpecializationTypeLoc.)
