Auto merge of #8111 - gilles-leblanc:issue-8002, r=SimonSapin
Compute value of float according to position value According to CSS2 Section 9.7, if 'position' has a value of 'absolute' or 'fixed' the computed value of 'float' should be 'none'. This changes the float to a single_keyword_computed which checks the positioned value of the element to compute the float value. Fixes #8002 <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.png" height=40 alt="Review on Reviewable"/>](https://reviewable.io/reviews/servo/servo/8111) <!-- Reviewable:end -->
