layout: Correctly take the inline size of cleared floats into account

Browse source 
when estimating the inline size of block formatting contexts.

The speculated inline-size of the preceding floats was forced to zero at
the wrong time if the float was itself cleared, causing it to overwrite
the speculated value. Shuffling the code around a bit fixes the problem.
