Make RULES more robust in GHC.Float
The RULES that use hand-written specialised code for overloaded class
methods like floor, ceiling, truncate etc were fragile to certain
transformations. This patch makes them robust. See #19582.
It's all described in Note [Rules for overloaded class methods].
No test case because currently we don't do the transformation
(floating out over-saturated applications) that makes this patch
have an effect. But we may so so in future, and this patch makes
the RULES much more robust.
