[DebugInfo][DWARF] Use DW_AT_call_target_clobbered for exprs with volatile regs (#172167)
Without this patch DW_AT_call_target is used for all indirect call address
location expressions. The DWARF spec says:
For indirect calls or jumps where the address is not computable without use
of registers or memory locations that might be clobbered by the call the
DW_AT_call_target_clobbered attribute is used instead of the
DW_AT_call_target attribute.
This patch implements that behaviour.
[GlobalISel](NFC) Refactor construction of LLTs in `LegalizerHelper` (#170664)
I spotted a number of places where we're duplicating logic provided by
the `LLT` class inline in `LegalizerHelper`. This PR tidies up these
spots.
[IR] Optimzie `PHINode::removeIncomingValue()` by swapping with the last of incoming value.
Add an optional argument `KeepIncomingOrder` defaults false, when `KeepIncomingOrder` is false,
the new implementation simply moves the last incoming value and block into the position of the element being removed.
This improve compile-time for PHI nodes with many predecessors.
[libcxx][docs] Fix boostrapping build configure command (#172015)
If I take the command from the page and add my triple like so:

[AArch64]Enable aggressive interleaving for A320 (#169825)
This patch makes use of aggressive interleaving options for the A320
subtarget. This is done by adding a new local parameter to the
AArch64Subtarget class. With this enabled we see an aggregate uplift of
0.7% on internal benchmark suites with up to 51% uplift on individual
benchmark workloads.
[llvm][examples] Disable some JIT examples when threading is disabled (#172282)
This fixes an error on our Armv8 bot:
```
<...>/RemoteJITUtils.cpp:132:24: error: use of undeclared identifier 'DynamicThreadPoolTaskDispatcher'
132 | std::make_unique<DynamicThreadPoolTaskDispatcher>(std::nullopt),
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
These examples require LLVM_ENABLE_THREADS to be ON, and cannot run
otherwise. As a comment says elsewhere:
```
// Out of process mode using SimpleRemoteEPC depends on threads.
```
[libc++] Fix std::for_each(associative-container) not using std:invoke and projections (#171984)
#164405 added specializations of `for_each` that didn't do the ranges
call shenanigans, but instead just did what the classic algorithms have
to do. This updates the calls to work for the ranges overloads as well.
[clang][NVPTX] Add support for mixed-precision FP arithmetic (#168359)
This change adds support for mixed precision floating point
arithmetic for `f16` and `bf16` where the following patterns:
```
%fh = fpext half %h to float
%resfh = fp-operation(%fh, ...)
...
%fb = fpext bfloat %b to float
%resfb = fp-operation(%fb, ...)
where the fp-operation can be any of:
- fadd
- fsub
- llvm.fma.f32
- llvm.nvvm.add(/fma).*
```
are lowered to the corresponding mixed precision instructions which
combine the conversion and operation into one instruction from

[VPlan] Directly unroll VectorPointerRecipe (#168886)
In an effort to get rid of VPUnrollPartAccessor and directly unroll
recipes, start by directly unrolling VectorPointerRecipe, allowing for
VPlan-based simplifications and simplification of the corresponding
execute.
[libc++] Remove unused __parent_pointer alias from __tree and map (#172185)
The `__parent_pointer` type alias was marked to be removed in
d163ab3323495560eb0255ac807da2bf24d3c629.
At that time, <map> still had uses of `__parent_pointer` as a local
variable type in operator[] and at()
Those uses were removed in 4a2dd31f16d60b65a46696a909efad5c11b18c19,
which refactored `__find_equal` to return a pair instead of using an out
parameter
However, the typedef in <map> and the alias in __tree were left behind
This patch removes the unused typedef from <map> and the
`__parent_pointer` alias from __tree

AMDGPU/GlobalISel: Regbanklegalize for G_CONCAT_VECTORS (#171471)
RegBankLegalize using trivial mapping helper, assigns same reg bank
to all operands, vgpr or sgpr.
Uncovers multiple codegen and regbank combiner regressions related to
looking through sgpr to vgpr copies.
Skip regbankselect-concat-vector.mir since agprs are not yet supported.
[mlir:bazel] Fix missing dependency introduced in #171727. (#172267)
That PR added an include to `LLVMOps.td` without adding a target
providing that file. Curiously, this does not break the official builds
but it *does* break my bazel build.

llvm: Export IndexedCodeGenDataLazyLoading (#169563)
This is needed so the llvm-cgdata tool properly builds with
`LLVM_BUILD_LLVM_DYLIB` so LLVM can be built as a DLL on Windows.
This effort is tracked in #109483.
