Bob Wilson 63c931443d Move the special-case check from r240462 into ARM-specific code.
This fixes a serious bug in r240462: checking the BuiltinID for
ARM::BI_MoveToCoprocessor* in EmitBuiltinExpr() ignores the fact that
each target has an overlapping range of the BuiltinID values. That check
can trigger for builtins from other targets, leading to very bad
behavior.

Part of the reason I did not implement r240462 this way to begin with is
the special handling of the last argument for Neon builtins. In this
change, I have factored out the check to see which builtins have that
extra argument into a new HasExtraNeonArgument() function. There is still
some awkwardness in having to check for those builtins in two separate
places, i.e., once to see if the extra argument is present and once to
generate the appropriate IR, but this seems much cleaner than my previous
patch.

//===----------------------------------------------------------------------===//
// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
