libLLVM: Revert update to 5.0.0

The update broke MesaLib, which blocks a vast number of packages.  In
the interest of stability heading towards 2017Q4, revert it, leaving
the issue of how to handle updates to this package (how much testing
is required, keeping multiple versions, etc.) to after the branch.

Log message:
llvm: updated to 5.0.0

5.0.0:
Non-comprehensive list of changes in this release
* LLVM’s WeakVH has been renamed to WeakTrackingVH and a new WeakVH has been \ 
introduced. The new WeakVH nulls itself out on deletion, but does not track \ 
values across RAUW.
* A new library named BinaryFormat has been created which holds a collection of \ 
code which previously lived in Support. This includes the file_magic structure \ 
and identify_magic functions, as well as all the structure and type definitions \ 
for DWARF, ELF, COFF, WASM, and MachO file formats.
* The tool llvm-pdbdump has been renamed llvm-pdbutil to better reflect its \ 
nature as a general purpose PDB manipulation / diagnostics tool that does more \ 
than just dumping contents.
* The BBVectorize pass has been removed. It was fully replaced and no longer \ 
used back in 2014 but we didn’t get around to removing it. Now it is gone. The \ 
SLP vectorizer is the suggested non-loop vectorization pass.
* A new tool opt-viewer.py has been added to visualize optimization remarks in \ 
HTML. The tool processes the YAML files produced by clang with the \ 
-fsave-optimization-record option.
* A new CMake macro LLVM_REVERSE_ITERATION has been added. If enabled, all \ 
supported unordered LLVM containers would be iterated in reverse order. This is \ 
useful for uncovering non-determinism caused by iteration of unordered \ 
containers. Currently, it supports reverse iteration of SmallPtrSet and \ 
DenseMap.
* A new tool llvm-dlltool has been added to create short import libraries from \ 
GNU style definition files. The tool utilizes the PE COFF SPEC Import Library \ 
Format and PE COFF Auxiliary Weak Externals Format to achieve compatibility with \ 
LLD and MSVC LINK.
