[PATCH] Don't Promote x86_fp80 byval Pointer Arguments

[Thomas Jablin]

As per request, I have modified the comments to use \brief, added full-stops at the ends of sentences, and modified the unit tests to search for whole prototypes. Please let me know if any additional modifications are necessary. Otherwise, could you please push this upstream?
