The instruction addi is usually used to post increase the loop indvar, which looks like this:

goto label_X
However, for PowerPC, if there are too many vsx instructions that between y = op x and i = addi i, 1,
it will use all the hw resource that block the execution of i = addi, i, 1, which result in the stall
of the load instruction in next iteration. So, a heuristic is added to move the addi as early as possible
to have the load hide the latency of vsx instructions, if other heuristic didn't apply to avoid the starve.

Support build-ids of other sizes than 16 in UUID::SetFromStringRef
SBTarget::AddModule currently handles the UUID parameter in a very
weird way: UUIDs with more than 16 bytes are trimmed to 16 bytes. On
the other hand, shorter-than-16-bytes UUIDs are completely ignored. In
this patch, we change the parsing code to handle UUIDs of arbitrary

To support arbitrary size UUIDs in SBTarget::AddModule, this patch
changes UUID::SetFromStringRef to parse UUIDs of arbitrary length. We
subtly change the semantics of SetFromStringRef - SetFromStringRef now
only succeeds if the entire input is consumed to prevent some
prefix-parsing confusion. This is up for discussion, but I believe
this is more consistent - we always return false for invalid UUIDs
rather than sometimes truncating to a valid prefix. Also, all the
call-sites except the API and interpreter seem to expect to consume
the entire input.
This also adds tests for adding existing modules 4-, 16-, and 20-byte
build-ids. Finally, we took the liberty of testing the minidump
scenario we care about - removing placeholder module from minidump and
replacing it with the real module.

MachineBasicBlock::updateTerminator now requires an explicit layout successor.
Previously, it tried to infer the correct destination block from the
successor list, but this is a rather tricky propspect, given the
existence of successors that occur mid-block, such as invoke, and
potentially in the future, callbr/INLINEASM_BR. (INLINEASM_BR, in
particular would be problematic, because its successor blocks are not
distinct from "normal" successors, as EHPads are.)
Instead, require the caller to pass in the expected fallthrough
successor explicitly. In most callers, the correct block is
immediately clear. But, in MachineBlockPlacement, we do need to record
the original ordering, before starting to reorder blocks.
Unfortunately, the goal of decoupling the behavior of end-of-block
jumps from the successor list has not been fully accomplished in this
patch, as there is currently no other way to determine whether a block
is intended to fall-through, or end as unreachable. Further work is
needed there.

AMDGPU/GlobalISel: Start rewriting load/store legality rules
The current set is an incomprehensible mess riddled with ordering
hacks for various limitations in the legalizer at the time of writing,
many of which have been fixed. This takes a very small step in
correcting this.
The core first change is to start checking for fully legal cases
first, rather than trying to figure out all of the actions that could
need to be performed. It's recommended to check the legal cases first
for faster legality checks in the common case. This still has a table
listing some common cases, but it needs measuring whether this really
helps or not.
More significantly, stop trying to allow any arbitrary type with a
legal bitwidth as a legal memory type, and start using the bitcast
legalize action for them. Allowing loads of these weird vector types
produced new burdens we don't need for handling all of the
legalization artifacts. Unlike the SelectionDAG handling, this is
still not casting 64 or 16-bit element vectors to 32-bit
vectors. These cases should still be handled by increasing/decreasing
the number of 16-bit elements. This is primarily to fix 8-bit element
vectors.
Another change is to stop trying to handle the load-widening based on
a higher alignment. We should still do this, but the way it was
handled wasn't really correct. We really need to modify the MMO's size
at the same time, and not just increase the result type. The
LegalizerHelper does not do this, and I think this would really
require a separate WidenMemory action (or to add a memory action
payload to the LegalizeMutation). These will now fail to legalize.
The structure of the legalizer rules makes writing concise rules here
difficult. It would be easier if the same function could answer the
query the query, and report the action to perform at the same
time. Instead these two are split into distinct predicate and action
functions. This is mostly tolerable for other cases, but the
load/store rules get pretty complicated so it's difficult to keep two
versions of these functions in sync.

[SCEV] ScalarEvolution::createSCEV(): Instruction::Or: drop bogus no-wrap flag detection
Summary:
That's just really wrong. While sure, if LHS is AddRec, and we could
propagate it's no-wrap flags, that doesn't make, because as long as
the operands of `or` had no common bits set, then the `add`
of these operands will never overflow: http://volta.cs.utah.edu:8080/z/gmt7Sy
IOW we need no propagation/detection, we are free to just set NUW+NSW.
But as rG39e3683534c83573da5c8b70c8adfb43948f601f shows,
even when the old code failed to "deduce" flags,
we'd eventually re-deduce them somewhere, later.
So let's just set them.
