This patch adds support for including the avx512 mask register information in the mask/maskz versions of shuffle instruction comments.
This initial version just adds support for MOVDDUP/MOVSHDUP/MOVSLDUP to reduce the mass of test regenerations, other shuffle instructions can be added in due course.

PR28400 seems to be not an isolated issue, but a general problem related
to caching analyses. We will need to discuss on llvm-dev.
A test case is in the PR.

This actually uncovered a surprisingly large chain of ultimately unused
TLI args.
From what I can gather, this argument is a remnant of when
isKnownNonNull would look at the TLI directly.
The current approach seems to be that InferFunctionAttrs runs early in
the pipeline and uses TLI to annotate the TLI-dependent non-null
information as return attributes.
This also removes the dependence of functionattrs on TLI altogether.

This new chapter describes compiling LLVM IR to object files.
The new chaper is chapter 8, so later chapters have been renumbered.
Since this brings us to 10 chapters total, I've also needed to rename
the other chapters to use two digit numbering.

This could of course be a simple binary search with no global state
involved at all if someone cares enough. Just don't make everyone
linking the hexagon backend pay for it on process startup and shutdown.

Its not worth trying to write out tests for all the avx512f builtins yet, just adding tests for lowering of generic IR as we transition to it (shuffles mainly right now).

Summary:
Add renderscript32 and renderscript64 ArchTypes. This is to configure
the ABI requirement on 32-bit RenderScript that 'long' types have 64-bit
size and alignment. 64-bit RenderScript is the same as AArch64, but is
added here for completeness.

Given something like:
struct S {
int a;
struct { int b; };
};
We would fail to give 'b' offset 4. Instead, we would give it the
offset it has inside of it's struct.

A namespace without a name should be written out as `anonymous
namespace' while a tag type without a name should be written out as
<unnamed-tag>.

Due to visit order problems, in the case of an unaligned copy
the legalized DAG fails to eliminate extra instructions introduced
by the expansion of both unaligned parts.

Fix incorrect calculation of the type size for __msan_maybe_warning_N
call that resulted in an invalid (narrowing) zext instruction and
"Assertion `castIsValid(op, S, Ty) && "Invalid cast!"' failed."
Only happens in very large functions (with more than 3500 MSan
checks) operating on integer types that are not power-of-two.

There was a combine before to handle the simple copy case.
Split this into handling loads and stores separately.
We might want to change how this handles some of the vector
extloads, since this can result in large code size increases.

MSVC makes up names for these anonymous structs, but we don't (yet).
Eventually Clang should use getTypedefNameForAnonDecl() to put some name
in the debug info, and we can update the test case when that happens.

Summary:
GetBoundryInstruction returns the last instruction as the instruction which follows or end(). Otherwise the last instruction in the boundry set is not being tested by isVectorizable().
Partially solve reordering of instructions. More extensive solution to follow.
