[InstCombine] Allow fptrunc (fpext X)) to be reduced to a single fpext/ftrunc
If we are only truncating bits from the extend we should be able to just use a smaller extend.
If we are truncating more than the extend we should be able to just use a fptrunc since the presense of the fpextend shouldn't affect rounding.
