reimplement __sync_* builtins to be variadic and to follow the same semantic rules that gcc and icc use. This implements the variadic and concrete versions as builtins and has sema do the disambiguation. There are probably a bunch of details to finish up but this seems like a large monotonic step forward :) llvm-svn: 71212

Improve the representation of the atomic builtins in a few ways. First, we make their call expressions synthetically have the "deduced" types based on their first argument. We only insert conversions in the AST for arguments whose values require conversion to match the value type expected. This keeps PR7600 closed by maintaining the return type, but avoids assertions due to unexpected implicit casts making the type unsigned (test case added from Daniel). The magic is moved into the codegen for the atomic builtin which inserts the casts as needed at the IR level to raise the type to an integer suitable for the LLVM intrinsic. This shouldn't cause any real change in functionality, but now we can make the builtin be more truly polymorphic. llvm-svn: 108638

Improve the representation of the atomic builtins in a few ways. First, we make their call expressions synthetically have the "deduced" types based on their first argument.
