[PATCH] Caller/Calllee unsafe-fp-math attribute fixup prior to inlining.

[Puyan Lotfi]

The following patch checks that a caller with unsafe-fp-math set does get a callee inlined into it that does not have the attribute set without unsetting attribute in the caller prior; idea is to make the caller being altered by inlining be as safe as the callee. 

Test case included in patch. 

Could someone review this?

Thanks
