Peter Collingbourne ddbe4544b8 [dfsan] Abort at runtime on indirect calls to uninstrumented vararg functions.

We currently have no infrastructure to support these correctly.

This is accomplished by generating a call to a runtime library function that
aborts at runtime in place of the regular wrapper for such functions. Direct
calls are rewritten in the usual way during traversal of the caller's IR.

We also remove the "split-stack" attribute from such wrappers, as the code
generator cannot currently handle split-stack vararg functions.

Inputs

DebugInfo+DFSan: Ensure that debug info references to llvm::Functions remain pointing to the underlying function when wrappers are created
