When launching argdumper, there are a few problems with the
current logic. First, on Windows, the file is called
argdumper.exe, not argdumper. Second, Windows paths have
backslashes in them, and JSON treats <backslash><char> as an
escape sequence. To fix the second problem, on Windows we
convert backslashes to forward slashes, since backslash isn't
a valid filename character anyway this shouldn't be a problem.

It turns out that `count: -1` is a special value indicating an empty
array, such as `Values` in:
struct T {
unsigned Count;
int Values[];
};
Handle it.

llvm::StringRef doesn't make a copy of a string, it just holds a
reference. When special_directions_stream went out of scope,
special_directions was holding on to a stale pointer.
Moving special_directions_stream into a higher scope to keep
special_directions pointing to a valid string.

target.error-path (and output-path) were getting resolved on the
local file system, which doesn't make any sense for remote targets
So this patch prevents file paths from being resolved on the host
system.

Weak aliases defined using /alternatename command line option were getting
wrong RVAs in the final output because of wrong atom ordinal. Alias atoms
were assigned large ordinals than any other regular atoms because they were
instantiated after other atoms and just got new (larger) ordinals.
Atoms are sorted by its file and atom ordinals in the order pass. Alias
atoms were located after all other atoms in the same file.
An alias atom's ordinal needs to be smaller than its alias target but larger
than the atom appeared before the target -- so that the alias is located
between the two. Since an alias has no size, the alias target will be located
at the same location as the alias.
In this patch, I made a gap between two regular atoms so that we can put
aliases after instantiating them (without re-numbering existing atoms).

VOP2 declares vsrc1, but VOP3 declares src1.
We can't use the same "ins" if the operands have different names in VOP2
and VOP3 encodings.
This fixes a hang in geometry shaders which spill M0 on VI.
(BTW it doesn't look like M0 needs spilling and the spilling seems
duplicated 3 times)

atomContent's memory is freed at the end of the stack frame,
but it is referenced by the atom pushed into _definedAtoms.

The coverage mapping generation code previously generated a large
number of redundant coverage regions and then tried to merge similar
ones back together. This then relied on some awkward heuristics to
prevent combining of regions that were importantly different but
happened to have the same count. The end result was inefficient and
hard to follow.
Now, we more carefully create the regions we actually want. This makes
it much easier to create regions at precise locations as well as
making the basic approach quite a bit easier to follow. There's still
a fair bit of complexity here dealing with included code and macro
expansions, but that's pretty hard to avoid without significantly
reducing the quality of data we provide.
I had to modify quite a few tests where the source ranges became more
precise or the old ranges seemed to be wrong anyways, and I've added
quite a few new tests since a large number of constructs didn't seem
to be tested before.

Put the name before the value in assembly for `MDEnum`. While working
on the testcase upgrade script for the new hierarchy, I noticed that it
"looks nicer" to have the name first, since it lines the names up in the
(somewhat typical) case that they have a common prefix.

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

Tests fail intermittently on FreeBSD and Linux, apparently due to
threading race conditions in lldb-mi.

The scope/context is always the compile unit, which we replace with
`nullptr` anyway (via `getNonCompileUnitScope()`). Drop it explicitly.
I noticed this field was always null while writing testcase upgrade
scripts to transition to the new hierarchy. Seems wasteful to
transition it over if it's already out-of-use.

This reverts commit r229665. It seems that the AArch64 ASAN tests, that
pass on all our internal machines, doesn't like the public buildbot.
Turning this off until we can investigate the public bot for a better
understanding.

`DIImportedEntity::getEntity()` currently returns a `DIScopeRef`, but
the nodes it references aren't always `DIScope`s. In particular, it can
reference global variables.
Introduce `DIDescriptorRef` to avoid the lie.

Don't spend the entire iteration space in the scalar loop prologue if
computing the trip count overflows. This change also gets rid of the
backedge check in the prologue loop and the extra check for
overflowing trip-count.

Summary:
* add_llvm_tool and add_llvm_library now add install-${name} targets to install specific components
* added installhdrs target to install just the LLVM headers
* The above changes only apply for single-configuration generators (Ninja, Makefiles...), not for multi-configuration generators (Visual Studio, Xcode...)

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.
