particular. Thanks to duncan for providing a great testcase.

drop attributes on varargs call arguments. Also, it could generate
invalid IR if the transformed call already had the 'nest' attribute
somewhere (this can never happen for code coming from llvm-gcc,
but it's a theoretical possibility). Fix both problems.

Fix the miscompilation of MiBench/consumer-lame that was exposed by Evan's2008-01-14T02:09:12ZChris Lattnersabre@nondot.org2008-01-14T02:09:12Zurn:sha1:941db495b8233a3753ce72a84021f677073ff4ea
byval work. This miscompilation is due to the program indexing an array out
of range and us doing a transformation that broke this.
