glob can return files in arbitrary order which breaks deterministic
builds. Rather, use `ar t` to list the files in each archive and
preserve the original order. Using `ar q` results in duplicate entries
in the archive, instead use `ar r` to avoid duplicates.

`CallBase` class rather than `CallSite` wrappers.
I pushed this change down through most of the statepoint infrastructure,
completely removing the use of CallSite where I could reasonably do so.
I ended up making a couple of cut-points: generic call handling
(instcombine, TLI, SDAG). As soon as it hit truly generic handling with
users outside the immediate code, I simply transitioned into or out of
a `CallSite` to make this a reasonable sized chunk.

Now that we have vector support for [US](ADD|SUB)O we no longer
need to scalarize when expanding [US](ADD|SUB)SAT.
This matches what the cost model already does.

Now that we have SimplifyDemandedBits support for funnel shifts (rL353539), we need to simplify funnel shifts back to bitshifts in cases where either argument has been folded to undef/zero.

I've avoided 'modulo' masks as we'll SimplifyDemandedBits those in the future, and we just need to check that the shift variable is 'in range'

Summary: Replace 0xc9 (LEAVE) with 0xcb (RETF) in ret_pattern_p(). Also put 0xc3 first, since it is the most common form and will match first.

256-bit horizontal math ops are an x86 monstrosity (and thankfully have
not been extended to 512-bit AFAIK).
The two 128-bit halves operate on separate halves of the inputs. So if we
don't demand anything in the upper half of the result, we can extract the
low halves of the inputs, do the math, and then insert that result into a
256-bit output.
All of the extract/insert is free (ymm<-->xmm), so we're left with a
narrower (cheaper) version of the original op.
In the affected tests based on:
https://bugs.llvm.org/show_bug.cgi?id=33758https://bugs.llvm.org/show_bug.cgi?id=38971
...we see that the h-op narrowing can result in further narrowing of other
math via existing generic transforms.
I originally drafted this patch as an exact pattern match starting from
extract_vector_elt, but I thought we might see diffs starting from
extract_subvector too, so I changed it to a more general demanded elements
solution. There are no extra existing regression test improvements from
that switch though, so we could go back.

SimplifySetCC still has much room for improvement, but this should
fix the remaining problem examples from:
https://bugs.llvm.org/show_bug.cgi?id=40657
The initial fix for this problem was rL353615.

This was introduced by me in r353613.
I tried to fix Big-endian bot and replaced
uintX_t -> ELFT::Xword. But ELFT::Xword is a packed<uint64_t>,
so it is always 8 bytes and that was obviously incorrect.
My intention was to use something like packed<uint> actually, which
size is target dependent.
Patch fixes this bug and adds a test case, since no bots seems reported this.

Different versions of python print dictionaries in different orders.
This can mess up diffs when updating ABI lists. This patch uses
pprint.pformat to print the dicts to get a consistent ordering.

The itoa symbols were added and their addition is documented in the CHANGELOG.
I'm not sure why the valarray symbols were missing previously, but they're
present in the v1 ABI lists and should be here as well.

The various EltSize, Offset, DataLayout, and StructLayout arguments
are all computable from the Address's element type and the DataLayout
which the CGBuilder already has access to.
After having previously asserted that the computed values are the same
as those passed in, now remove the redundant arguments from
CGBuilder's Create*GEP functions.

As discussed on D57389, this is a first step towards moving the SHLD/SHRD matching code to DAGCombiner using FSHL/FSHR instead.
There's a bit of work to do before I can do that, so this just folds to FSHL/FSHR in the existing code (handling the different SHRD/FSHR argument ordering), which fixes the issue we had with i16 shift amounts not being correctly masked.
