New Revision: 46215

URL: http://llvm.org/viewvc/llvm-project?rev=46215&view=rev
Log:
Merge from mainline.
Need to handle any 'nest' parameter before integer
parameters, since otherwise it won't be passed in
the right register.  With this change trampolines
work on x86-64 (thanks to Luke Guest for providing
access to an x86-64 box).
