to use SSE code instead (mantis #28366)

with valreal as parameter type, so the argument will always be

extended -> remove the typeconversion to extended if any; not done

in ninl, because there are other code generators that assume that

the parameter to trunc has been converted to valreal (e.g. PowerPC).
|
|
|
|
We can always remove such typeconversions here if they exist, because

on the x87 all floating point types are handled the same, and

if we call the inherited version we'll insert a call node, which

will insert the necessary type conversion again }
