Yes, it looks like it gets dropped into %r11, but not used from that
location.

We need to find out when the codegen loses track of the fact that %r11 has
applyFFTempFun.  Could you compile with "-native-commented 6"?  That's the
most debugging information that we can get from a precompiled MLton binary.
It produces a *lot* of debugging information (in the form of comments in the
assembly).  Rather than posting to the mailing list, I suggest posting the
basic block to http://mlton.org/TemporaryUpload.
