The following changes have been applied:
- Removed 'align 4'. We can simplify this away, as it does not provide useful
information in the example.
- Use named instructions instead of '%0'. This is nicer, but more importantly
this makes the IR valid. Before we had two assignments to %0 in a single
example.
- Add a missing branch instruction to make the loop structure clear.
- Move one access into outer.for.body to make it not look that empty.
- The statments that are only in the outer loop body should not reference the
inner loop metadata, but only the outer loop. Only statements in both loops
should reference both surrounding loops.
- Rename the array indexes to make them all independent. Before there were
identical array indexes in the inner and the outer loop. We want to
avoid this special case as it may lead to confusion.

already lived there and it is where it belongs -- this is the in-memory
debug location representation.
This is just cleanup -- Modules can actually cope with this, but that
doesn't make it right. After chatting with folks that have out-of-tree
stuff, going ahead and moving the rest of the headers seems preferable.

This will allow external callers of these functions to switch over time
rather than forcing a breaking change all a once. These particular
functions were determined by building clang/lld/lldb.

to ensure we don't mess up any of the overrides. Necessary for cleaning
up the Value use iterators and enabling range-based traversing of use
lists.

Patchpoints already did this. Doing it for stackmaps is a convenience
for the runtime in the event that it needs to scratch register to
patch or perform a runtime call thunk.
Unlike patchpoints, we just assume the AnyRegCC calling
convention. This is the only language and target independent calling
convention specific to stackmaps so makes sense. Although the calling
convention is not currently used to select the scratch registers.

selection dag (PR19012)
In X86SelectionDagInfo::EmitTargetCodeForMemcpy we check with MachineFrameInfo
to make sure that ESI isn't used as a base pointer register before we choose to
emit rep movs (which clobbers esi).
The problem is that MachineFrameInfo wouldn't know about dynamic allocas or
inline asm that clobbers the stack pointer until SelectionDAGBuilder has
encountered them.
This patch fixes the problem by checking for such things when building the
FunctionLoweringInfo.

The distinction between "identified" and "literal" struct types is fully
documented in a later section.

itself and teach it to convert between the non-const and const variants.
De-templatetize its usage in APIs to just use the const variant which
always works for those use cases. Also, rename its implementation to
reflect that it is an iterator over *users* not over *uses*.
This is a step toward providing both iterator and range support for
walking the *uses* distinct from the *users*. In a subsequent patch this
will get renamed to make it clear that this is an adaptor over the
fundamental use iterator.

using a full uint16_t with the flag value... which happens to be
0 or 1. Update the class for bool values and rename functions slightly.

Looks like llvm-readobj is the only customer of this code, and apparently
there's no test to cover this function. I'll write it after finishing
plumbing from llvm-objdump to there.

Currently this code is duplicated across visitSHL, visitSRA and visitSRL. The
plan is to add rotates as clients to this new function.
There is no functional change intended here.

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.
