[Power9] Part-word VSX integer scalar loads/stores and sign extend instructions

This patch removes the VSHRC register class (based on D20310) and adds
exploitation of the Power9 sub-word integer loads into VSX registers as well
as vector sign extensions.
The new instructions are useful for a few purposes:
Int to Fp conversions of 1 or 2-byte values loaded from memory
Building vectors of 1 or 2-byte integers with values loaded from memory
Storing individual 1 or 2-byte elements from integer vectors

[cmake] Reintroduce (ldconfig-compatible) SOVERSIONs on shared libraries
Reintroduce versioning of shared libraries via SOVERSION, addressing
the issues with the previous design, since Gentoo is relying
on shared-split install of LLVM. The SOVERSIONs were originally
introduced in r229720 for all libraries, and removed in r252093 in favor
of custom SONAME. As far as I understand, the major concern with the old
versioning was that the used versions were incompatible with ldconfig.
Having considered that, this commit introduce SOVERSIONS with the
following considerations:
1. SOVERSIONs are formed of major & minor version concatenated -- i.e.
for 4.0 its .so.40. This matches the common practice where the first
version number indicates ABI breakage, and therefore fixes the issues
with ldconfig. Additionally, VERSION with the remaining verion
components appended is used, however this is not strictly necessary.
2. The versioning is only applied to libraries with no explicit SONAME
specified -- i.e. it won't apply to libLLVM but only to the split
libraries. It will also apply to libraries installed by the subprojects.
3. The versioning is only done on *nix systems, Darwin excluded. This
matches the current use of SONAME.

Codegen: Tail-duplicate during placement.
The tail duplication pass uses an assumed layout when making duplication
decisions. This is fine, but passes up duplication opportunities that
may arise when blocks are outlined. Because we want the updated CFG to
affect subsequent placement decisions, this change must occur during
placement.
In order to achieve this goal, TailDuplicationPass is split into a
utility class, TailDuplicator, and the pass itself. The pass delegates
nearly everything to the TailDuplicator object, except for looping over
the blocks in a function. This allows the same code to be used for tail
duplication in both places.
This change, in concert with outlining optional branches, allows
triangle shaped code to perform much better, esepecially when the
taken/untaken branches are correlated, as it creates a second spine when
the tests are small enough.

Refactor the Args class.
There were a number of issues with the Args class preventing
efficient use of strings and incoporating LLVM's StringRef class.
The two biggest were:
1. Backing memory stored in a std::string, so we would frequently
have to use const_cast to get a mutable buffer for passing to
various low level APIs.
2. backing std::strings stored in a std::list, which doesn't
provide random access.
I wanted to solve these two issues so that we could provide
StringRef access to the underlying arguments, and also a way
to provide range-based access to the underlying argument array
while still providing convenient c-style access via an argv style
const char**.
The solution here is to store arguments in a single "entry" class
which contains the backing memory, a StringRef with precomputed
length, and the quote char. The backing memory is a manually
allocated const char* so that it is not invalidated when the
container is resized, and there is a separate argv array provided
for c-style access.

[CUDA] Disallow overloading destructors.
Summary:
We'd attempted to allow this, but turns out we were doing a very bad
job. :)
Making this work properly would be a giant change in clang. For
example, we'd need to make CXXRecordDecl::getDestructor()
context-sensitive, because the destructor you end up with depends on
where you're calling it from.
For now (and hopefully for ever), just disallow overloading of
destructors in CUDA.

This should fix:
https://llvm.org/bugs/show_bug.cgi?id=30433

1. Should we let scalar ops be scalars and avoid vector constant loads/splats?
2. Should we have a pass to combine constants such as the inverted pair that we have here?

Don't drop the llvm. prefix when renaming.
If the llvm. prefix is dropped other parts of llvm don't see this as
an intrinsic. This means that the number of regular symbols depends
on the context the module is loaded into, which causes LTO to abort.

[ARC] Ignore qualifiers in copy-restore expressions
When ARC is enabled, an ObjCIndirectCopyRestoreExpr models the passing
of a function argument s.t:
* The argument is copied into a temporary,
* The temporary is passed into the function, and
* After the function call completes, the temporary is move-assigned
back to the original location of the argument.
The argument type and the parameter type must agree "except possibly in
qualification". This commit weakens an assertion in EmitCallArg() to
actually reflect that.

That was caused by the optimisation incorrectly triggering on i64 ints, which

legalization and this optimisation in a loop. A native ARM compiler and testing
