Unwind info contents were indented at the same level as function table
contents. That's a bit confusing because the unwind info is pointed by
function table. In other places we usually increment indentation depth
by one when dereferncing a pointer.
This patch also removes extraneous newlines between function tables.

This is required to include MSVC's <atomic> header, which we do now in
LLVM.
Tests forthcoming in Clang, since that's where we test semantic inline
asm changes.

Register the Asm Printer for the ppc64le target.
This fills in a spot that was missed in an earlier change (r187179).

Previously for:
tail call void inttoptr (i64 65536 to void ()*)() nounwind
We would emit:
bl 65536
The immediate operand of the bl instruction is a relative offset so it is
wrong to use the absolute address here.

source file had already been moved. Also move the unittest into the IR
unittest library.
This may seem an odd thing to put in the IR library but we only really
use this with instructions and it needs the LLVM context to work, so it
is intrinsically tied to the IR library.

PassInfo structures of the legacy pass manager. Also give it the Legacy
prefix as it is not a particularly widely used header.

a bit surprising, as the class is almost entirely abstracted away from
any particular IR, however it encodes the comparsion predicates which
mutate ranges as ICmp predicate codes. This is reasonable as they're
used for both instructions and constants. Thus, it belongs in the IR
library with instructions and constants.

this would have been required because of the use of DataLayout, but that
has moved into the IR proper. It is still required because this folder
uses the constant folding in the analysis library (which uses the
datalayout) as the more aggressive basis of its folder.

directly care about the Value class (it is templated so that the key can
be any arbitrary Value subclass), it is in fact concretely tied to the
Value class through the ValueHandle's CallbackVH interface which relies
on the key type being some Value subclass to establish the value handle
chain.
Ironically, the unittest is already in the right library.

Move the test for this class into the IR unittests as well.
This uncovers that ValueMap too is in the IR library. Ironically, the
unittest for ValueMap is useless in the Support library (honestly, so
was the ValueHandle test) and so it already lives in the IR unittests.
Mmmm, tasty layering.

name might indicate, it is an iterator over the types in an instruction
in the IR.... You see where this is going.
Another step of modularizing the support library.

business.
This header includes Function and BasicBlock and directly uses the
interfaces of both classes. It has to do with the IR, it even has that
in the name. =] Put it in the library it belongs to.
This is one step toward making LLVM's Support library survive a C++
modules bootstrap.

out-of-line so that it can refer to the methods on User. As
a consequence, this removes the need to define one template method if
value_use_iterator in the extremely strange User.h header (!!!).
This makse Use.h slightly less peculiar. The only remaining real
peculiarity is the definition of Use::set in Value.h

inconsistent both with itself and with LLVM at large with formatting.
The *s were on the wrong side, the indent was off, etc etc. This is much
cleaner.
Also, go clang-format laying out the array of tags in nice columns.

The original code does not work correctly on executable files because the
code is written in such a way that only object files are assumed to be given
to llvm-objdump.
Contents of RuntimeFunction are different between executables and objects. In
executables, fields in RuntimeFunction have actual addresses to unwind info
structures. On the other hand, in object files, the fields have zero value,
but instead there are relocations pointing to the fields, so that Linker will
fill them at link-time.
So, when we are reading an object file, we need to use relocation info to
find the location of unwind info. When executable, we should just look at the
values in RuntimeFunction.

We were dropping the displacement on the floor if we also had some
immediate offset.
Should fix PR19033.
