CSS calc parsing stage

CSS calc parsing stage
https://bugs.webkit.org/show_bug.cgi?id=57082

This is the parsing stage of calc. The expressions are evaluated and
expression trees are generated. CSS values are not created yet - that
will happen in a subsequent commit.

Reviewed by David Hyatt.

No functional change - covered by existing tests in LayoutTests/css3/calc.
