The output here may not be optimal (yet), but it should be
consistent for commuted operands (it was not before) and
correct. We can do better by checking FMF and NaN if needed.
Code in InstSimplify generally assumes that we have already
folded code like this, so it was not handling 2 constant
inputs by commuting consistently.
Mitsuru Kariya reported the map operations insert_or_assign with a hint
violates the complexity requirement. The function no longer uses a lower_bound,
which caused the wrong complexity.

when -gsplit option is used with clang driver, clang driver will create
a filename with .dwo option based on the input file name and pass
it to clang -cc1. This file is used for storing the debug info. Since
HIP generate separate object files for different GPU arch's,
this file should be different for different GPU arch. This patch
adds _ and GPU arch to the stem of the dwo file.

We intend to replace heuristics based code completion ranking with a Decision Forest Model.
This patch introduces a format for representing the model and an inference runtime that is code-generated at build time.
- Forest.json contains all the trees as an array of trees.
- Features.json describes the features to be used.
- Codegen file takes the above two files and generates CompletionModel containing Feature struct and corresponding Evaluate function.
The Evaluate function maps a feature to a real number describing the relevance of this candidate.
- The codegen is part of build system and these files are generated at build time.
- Proposes a way to test the generated runtime using a test model.
- Replicates the model structure in unittests.
- unittest tests both the test model (for correct tree traversal) and the real model (for sanity).
This reverts commit 549e55b3d5.
Currently newer clang-format options cannot be included in .clang-format files, if not all users can be forced to use an updated version.
This patch tries to solve this by adding an option to clang-format, enabling to ignore unknown (newer) options.

We were breaking out of the switch which falls into the default
implementation of SimplifyDemandedBitsForTargetNode which is a
wrapper around computeKnownBits. So we end up doing the recursion
and known bits calculation all over again. Instead we should return
with the known bits we calculated in the switch.
When address sanitizing a function, stack unpinsoning code is inserted before each ret instruction. However if the ret instruciton is preceded by a musttail call, such transformation broke the musttail call contract and generates invalid IR.
This patch fixes the issue by moving the insertion point prior to the musttail call if there is one.

The IRInstructionData structs are a different representation of the
program. This list treats the program as if it was "flattened" and
the only parent is this list. This lets us easily create ranges of
instructions.

Enforcing a profile available check in the driver does not work with
incremental LTO builds where the LTO backend invocation does not include
the profile flags. At this point the profiles have already been consumed
and the IR contains profile metadata. Instead we always pass through the
-fsplit-machine-functions flag on user request. The pass itself contains
a check to return early if no profile information is available.

If the mask of a pdep or pext instruction is a shift masked (i.e. one contiguous block of ones) we need at most one and and one shift to represent the operation without the intrinsic. One all platforms I know of, this is faster than the pdep/pext.
The cost modelling for multiple contiguous blocks might be worth exploring in a follow up, but it's not relevant for my current use case. It would almost certainly be a win on AMDs where these are really really slow though.

This changes the order of output sections and the output assembly, but
is otherwise NFC.
It simplifies the TLOF interface by removing two COFF-only methods.
Currently, -object takes a comma separated list of objects as an
argument, which prevents it working with path names that contain a
comma. Drop comma-separated support, which requires to set pass the
-object flag multiple times to set multiple objects.
