Ahmed Bougacha 497ef8ab01 [TLI] Robustize SDAG LibFunc proto checking by merging it into TLI. 
This re-applies commit r292189, reverted in r292191.

SelectionDAGBuilder recognizes libfuncs using some homegrown
parameter type-checking.

Use TLI instead, removing another heap of redundant code.

This isn't strictly NFC, as the SDAG code was too lax.
Concretely, this means changes are required to a few tests:
- calling a non-variadic function via a variadic prototype isn't OK;
  it just happens to work on x86_64 (but not on, e.g., aarch64).
- mempcpy has a size_t parameter;  the SDAG code accepts any integer
  type, which meant using i32 on x86_64 worked.
- a handful of SystemZ tests check the SDAG support for lax prototype
  checking: Ulrich agrees on removing them.

I don't think it's worth supporting any of these (IMO) invalid
testcases.  Instead, fix them to be more meaningful.

Low Level Virtual Machine (LLVM)
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
