Add `replaceElements()`, `replaceVTableHolder()`, and
`replaceTemplateParams()` to `MDCompositeTypeBase`. Included an
assertion in `replaceElements()` to match the one in
`DICompositeType::replaceArrays()`.

This was leading to duplicate counts when a code region happened to
overlap exactly with an expansion. The combining behaviour only makes
sense for code regions.

This comes up when we generate coverage for a function but don't end
up emitting the function at all - dead static functions or inline
functions that aren't referenced in a particular TU, for example. In
these cases we'd like to show that the function was never called,
which is trivially true.

Make CoverageMapping easier to create, so that we can write targeted
unit tests for its internals, and add a some infrastructure to write
these tests. Finally, add a simple unit test for basic functionality.

Have the InstrProfWriter return a MemoryBuffer instead of a
std::string. This fixes the alignment issues the reader would hit, and
it's a more appropriate type for this anyway.
I've also removed an ugly helper function that's not needed since
we're allowing initializer lists now, and updated some error code
checks based on MSVC's issues with r229473.
This reverts r229483, reapplying r229478.

Add missing specialized node overloads for `MDNode::clone()` (they were
on most of the node types already, but missing from the others).
`MDNode::clone()` returns `TempMDNode` (`std::unique_ptr<MDNode,...>`),
while `TempMDSubrange::clone()` (for example) returns the more
convenient `TempMDSubrange` (`std::unique_ptr<TempMDSubrange,...>`).

This time we use a helper to format the assertion so we can just use
ASSERT_TRUE instead of relying on ASSERT_EQ being able to deal with
conversions between enum types.
This reverts r229496, re-applying r229473.

If any of the bots complain (perhaps due to an antiquated version of an STL implementation), I will revert.

This added API to the InstrProfWriter to write to a string so I could
write unittests without using temp files. This doesn't really work,
since the format has tighter alignment requirements than a char.
This reverts r229478 and its follow-up, r229481.

Add these tests again, but use va_list instead of initializer lists.

This required some minor API to be added to these types to avoid
needing temp files.
Also, I've used initializer lists in the tests, as MSVC 2013 claims to
support them. I'll redo this without them if the bots complain.

Introduces a subset of C++14 integer sequences in STLExtras. This is
just enough to support unpacking a std::tuple into the arguments of
snprintf, we can add more of it when it's actually needed.
Also removes an ancient macro hack that leaks a macro into the global
namespace. Clean up users that made use of the convenient hack.

LLVM's include tree and the use of using declarations to hide the
'legacy' namespace for the old pass manager.
This undoes the primary modules-hostile change I made to keep
out-of-tree targets building. I sent an email inquiring about whether
this would be reasonable to do at this phase and people seemed fine with
it, so making it a reality. This should allow us to start bootstrapping
with modules to a certain extent along with making it easier to mix and
match headers in general.
The updates to any code for users of LLVM are very mechanical. Switch
from including "llvm/PassManager.h" to "llvm/IR/LegacyPassManager.h".
Qualify the types which now produce compile errors with "legacy::". The
most common ones are "PassManager", "PassManagerBase", and
"FunctionPassManager".

Port `DIExpression::Operand` over to `MDExpression::ExprOperand`. The
logic is needed directly in `MDExpression` to support printing in
assembly.

0xFFFFFFFFFFFFFFFFLL doesn't fit in a long long so it should have
type 'unsigned long long'. MSVC thinks it's a (signed) __int64.

This makes llvm-pdbdump available on all platforms, although it
will currently fail to create a dumper if there is no PDB reader
implementation for the current platform.
It implements dumping of compilands and children, which is less
information than was previously available, but it has to be
rewritten from scratch using the new set of interfaces, so the
rest of the functionality will be added back in subsequent commits.

Add new API for converting temporaries that may self-reference.
Self-referencing nodes are not allowed to be uniqued, so sending them
into `replaceWithUniqued()` is dangerous (and this commit adds
assertions that prevent it).
`replaceWithPermanent()` has similar semantics to `get()` followed by
calls to `replaceOperandWith()`. In particular, if there's a
self-reference, it returns a distinct node; otherwise, it returns a
uniqued one. Like `replaceWithUniqued()` and `replaceWithDistinct()`
(well, it calls out to them) it mutates the temporary node in place if
possible, only calling `replaceAllUsesWith()` on a uniquing collision.

I noticed this fields were never used in r228607, but I neglected to
propagate that into `MDTemplateParameter` until now. This really should
have been done before commit in r228640; sorry for the churn.

Add specialized debug info metadata nodes that match the `DIDescriptor`
wrappers (used by `DIBuilder`) closely. Assembly and bitcode support to
follow soon (it'll mostly just be obvious), but this sketches in today's
schema. This is the first big commit (well, the only *big* one aside
from the testcase changes that'll come when I move this into place) for
PR22464.
I've marked a bunch of obvious changes as `TODO`s in the source; I plan
to make those changes promptly after this hierarchy is moved underneath
`DIDescriptor`, but for now I'm aiming mostly to match the status quo.

I just realized that the specialized metadata node patch I'm about to
commit won't compile on old compilers. Bump `hash_combine()`'s support
for non-variadic templates to 18 (I tested this by reversing the logic
in the #ifdef).

Dumping a symbol often requires access to data that isn't inside
the symbol hierarchy, but which is only accessible through the
top-level session. This patch is a pure interface change to give
symbols a reference to the session.

This patch implements a few of the optional suggestions from the
initial patch comitting libpdb. In particular, it implements a
virtual function out of line for each of the concrete classes.
A few other minor cleanups exist as well, such as using override
instead of virtual, etc.

These were originally submitted as part of r228428, but this part
caused a build breakage in LLVMConfig. The library portion was
resubmitted independently since it was not causing breakage.
There were two reasons this was causing the build to fail. The
first is that there were no Makefiles added for the PDB tests. And
the second is that the DebugInfoPDB library was only being built by
CMake behind an "if (MSVC)" check. This is wrong since this the
library hides platform specific details, and it was causing
LLVM-Config to not find the library when trying to build unittests.
