Revert: Detect floats to avoid or clear due to negative margin top (and followup)

This patch reverts the following two patches:
1) Detect floats to avoid or clear due to negative margin top
https://crrev.com/3c8d298acf826fc5337c526b1016a03b37c2656a
2) Stop searching for overhanging floats when the sibling's floats no longer overlap
https://crrev.com/eb8f963f9a5030c0007500620eefaad7c2c2c490

This revert is due to a perf regression in the layout of floats. A followup
patch will unskip the mossiella perf test that was skipped due to this
regression.
