Do not QuickFloor on cmsintrp
In this CL, the flag CMS_DONT_USE_FAST_FLOOR is set to true because quickfloor
could cause heap-buffer-overflow due to flooring errors. In the testcase for
the bug, Input[2] is a number very close but smaller than 1 such that
quickfloor returned 1 (whereas Input[2] >= 1.0 was false).
Bug: chromium:752725
