It seems we should give targets like darwin a permanent workaround for this
issue. Since config can't correctly determine in all cases whether an
implementation has a "fast enough" sincos/cexp, the few targets where the
current flags don't work should be able to disable the transformation.
I can create a cse-sincos option flag, set on by default for most platforms.
The darwin platform maintainer (and others, if necessary) could add
-fno-cse-sincos to the platform defaults.
Any concerns with this approach?
