25d72330ff [AMDGPU] Add .uniform_work_group_size metadata to v5
Amdgpu kernel with function attribute "uniform-work-group-size"="true" requires
uniform work group size (i.e. each dimension of global size is a multiple of
corresponding dimension of work group size). hipExtModuleLaunchKernel allows to
launch HIP kernel with non-uniform workgroup size, which makes it necessary for
runtime to check and enforce uniform workgroup size if kernel requires it. To
let runtime be able to enforce that, this metadata is needed to indicate that
the kernel requires uniform workgroup size.

20cde15415 [Target] Use std::nullopt instead of None (NFC)
This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated.  The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.

This is part of an effort to migrate from llvm::Optional to
std::optional:

ae0ba7dedd AMDGPU: Optimize out implicit kernarg argument allocation if unused
We already annotate whether llvm.amdgcn.implicitarg.ptr is known to be
unused. Start using it to avoid allocating the implicit arguments if
unneeded.

48958d02d2 [NFC][AMDGPU] Reduce includes dependencies.
1. Splitted out some parts of R600 target to separate modules/headers.
2. Reduced some include lists in headers.
3. Found and fixed issue with override `GCNTargetMachine::getSubtargetImpl()`
   and `R600TargetMachine::getSubtargetImpl()` had different return value type
   than base class.
4. Minor forward declarations cleanup.

1168119c2f AMDGPU: Start interpreting byref on kernel arguments
These are treated identically to value aggregates placed in the kernel
argument list. A %struct.foo or %struct.foo addrspace(4)*
byref(sizeof(%struct.foo)) align(alignof(%struct.foo)) argument should
produce the same offsets and argument metadata.

This handles all 3 kernel ABI implementations, and the two HSA
metadata emission paths.

31f4e43f3f AMDGPU: Remove .value_type from kernel metadata
This doesn't appear used for anything, and is emitted incorrectly
based on the description. This also depends on the IR type, and
pointee element type.

0eaee545ee [llvm] Migrate llvm::make_unique to std::make_unique
Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.
