The inliner bits looks fine to me. Of course it is easy to check whether the
function actually calls floor/ceil and thus is affected by this flag.  Do you
expect this to matter? I.e. do you expect that codebases will mix both values
of this flag in one project and expect cross-module inlining to work with LTO?
(Dealing with codegen flags in inliner is really painful. Basically I am trying
to do that on demand now - when I see it blocks inlining in one of larger 
project
I test. We will need better longer term strategry later I suppose.)
