Tim Northover dd9809dd72 Permit ABIs where the caller extends the result (test change).
This test was written to make sure *something* sane is generated, not
to test any ABI's signedness semantics.

This should allow the test to pass if AArch64 is the default target.

Eli Friedman 34866c7719 Change the representation of builtin functions in the AST
(__builtin_* etc.) so that it isn't possible to take their address.
Specifically, introduce a new type to represent a reference to a builtin
function, and a new cast kind to convert it to a function pointer in the
operand of a call.  Fixes PR13195.

Douglas Gregor e0e9630e07 When extracting the callee declaration from a call expression, be sure
to look through SubstNonTypeTemplateParmExprs. Then, update the IR
generation of CallExprs to actually use CallExpr::getCalleeDecl()
rather than attempting to mimick its behavior (badly).

Fixes <rdar://problem/10063539>.

Douglas Gregor 9246b6830a In C++, if the user redeclares a builtin function with a type that is
inconsistent with the type that the builtin *should* have, forget
about the builtin altogether: we don't want subsequence analyses,
CodeGen, etc., to think that we have a proper builtin function.

C is protected from errors here because it allows one to use a
library builtin without having a declaration, and detects inconsistent
(re-)declarations of builtins during declaration merging. C++ was
unprotected, and therefore would crash.

Fixes PR8839.
