so if we traversed through phi node then we do not need to keep information

Note that there could be some trickiness with these element-atomic intrinsics for the dataflow sanitizer in racy multithreaded programs. The data flow sanitizer inserts additional lib calls to mirror the memory intrinsic's action, so it is possible (very likely, even) that the dfsan buffers will not be in sync with the original buffers. Furthermore, implementation of the dfsan buffer updates for the element atomic intrinsics will have to also use unordered atomic instructions. If we can assume that dfsan is never run on racy multithreaded programs, then the element atomic memory intrinsics can pretty much be treated the same as the regular memory intrinsics.

I also noticed that the microsoft-pdb reference repository uses a basic

of that CRC ready to use, because it's used in COFF for ICF.
I'll make LLD call this hashing utility in a follow-up change. We might

[codeview] Remove TypeServerHandler and PDBTypeServerHandler

Instead of wiring these through the CVTypeVisitor interface, clients
should inspect the CVTypeArray before visiting it and potentially load
up the type server's TPI stream if they need it.
No tests relied on this functionality because LLD was the only client.

[SystemZ] Add support for IBM z14 processor (3/3)
This adds support for the new 128-bit vector float instructions of z14.
Note that these instructions actually only operate on the f128 type,
since only each 128-bit vector register can hold only one 128-bit
float value. However, this is still preferable to the legacy 128-bit
float instructions, since those operate on pairs of floating-point
registers (so we can hold at most 8 values in registers), while the
new instructions use single vector registers (so we hold up to 32
value in registers).
Adding support includes:
- Enabling the instructions for the assembler/disassembler.
- CodeGen for the instructions. This includes allocating the f128
type now to the VR128BitRegClass instead of FP128BitRegClass.
- Scheduler description support for the instructions.
Note that for a small number of operations, we have no new vector
instructions (like integer <-> 128-bit float conversions), and so
we use the legacy instruction and then reformat the operand
(i.e. copy between a pair of floating-point registers and a
vector register).

[X86] X86::CMOV to Branch heuristic based optimization.
LLVM compiler recognizes opportunities to transform a branch into IR select instruction(s) - later it will be lowered into X86::CMOV instruction, assuming no other optimization eliminated the SelectInst.
However, it is not always profitable to emit X86::CMOV instruction. For example, branch is preferable over an X86::CMOV instruction when:
1. Branch is well predicted
2. Condition operand is expensive, compared to True-value and the False-value operands
In CodeGenPrepare pass there is a shallow optimization that tries to convert SelectInst into branch, but it is not enough.
This commit, implements machine optimization pass that converts X86::CMOV instruction(s) into branch, based on a conservative heuristic.

Fix bot failures from r308114
Finally figured out that some bots were failing from r308114
with the message:
llvm-lto2: LTO::run failed: No available targets are compatible with this triple.
after adding in some other checking that finally caused this to show up
in the FileCheck output.
Added "REQUIRES: x86-registered-target" which should fix it.

Modify checks from r308114 even more, to see if I can narrow down

Restore with fix "[ThinLTO] Ensure we always select the same function copy to import"
This restores r308078/r308079 with a fix for bot non-determinisim (make
sure we run llvm-lto in single threaded mode so the debug output doesn't get
interleaved).

[IR] Implement Constant::isNegativeZeroValue/isZeroValue/isAllOnesValue/isOneValue/isMinSignedValue for ConstantDataVector without going through getElementAsConstant
Summary:
Currently these methods call ConstantDataVector::getSplatValue which uses getElementsAsConstant to create a Constant object representing the element value. This method incurs a map lookup to see if we already have created such a Constant before and if not allocates a new Constant object.
This patch changes these methods to use getElementAsAPFloat and getElementAsInteger so we can just examine the data values directly.

[InstCombine] Improve the expansion in SimplifyUsingDistributiveLaws to handle cases where one side doesn't simplify, but the other side resolves to an identity value
Summary:
If one side simplifies to the identity value for inner opcode, we can replace the value with just the operation that can't be simplified.
I've removed a couple now unneeded special cases in visitAnd and visitOr. There are probably other cases I missed.
