  [Clang] Implement P0963R3 "Structured binding declaration as a condition" (#130228)

This implements the R2 semantics of P0963.

The R1 semantics, as outlined in the paper, were introduced in Clang 6.
In addition to that, the paper proposes swapping the evaluation order of
condition expressions and the initialization of binding declarations
(i.e. std::tuple-like decompositions).

  [ConstantFolding] Fix handling of index width != pointer width (#130608)

Per LangRef:

> The offsets are then added to the low bits of the base address up to
the index type width, with silently-wrapping two’s complement
arithmetic. If the pointer size is larger than the index size, this
means that the bits outside the index type width will not be affected.

The transform as implemented was doubly wrong, because it just truncated
the original base pointer to the index width, losing the top bits
entirely. Make sure we preserve the bits and use wrapping arithmetic
within the low bits.

  [lldb][Mangled] Use early-return style in GetDemangledName (#130622)

This patch refactors `Mangled::GetDemangledName` to use LLVM's preferred
early-return style. I'm planning on introducing a way to force
re-demangling of names in a future patch, and this stylisitc cleanup
makes that easier to reason about.

Also performed small cleanups where I could:
* we can handle `eManglingSchemeNone` inside the switch instead of a
separate if-block
* removed some redundant explicit StringRef<->C-string conversions

  [lldb][XcodeSDK] Simplify logic that adjusts sysroot during XcodeSDK merging (#130640)

The `DW_AT_APPLE_sdk` should always be equal to the filename of the
`DW_AT_LLVM_sysroot`. We can use this property to simplify
`XcodeSDK::Merge` to no longer manually adjust the sysroot filename.
Instead we simply update the sysroot filename with merged SDK name.

This should be an NFC change.

  [flang] introduce fir.copy to avoid load store of aggregates (#130289)

Introduce a FIR operation to do memcopy/memmove of compile time constant size types.

This is to avoid requiring derived type copies to done with load/store
which is badly supported in LLVM when the aggregate type is "big" (no
threshold can easily be defined here, better to always avoid them for
fir.type).

This was the root cause of the regressions caused by #114002 which introduced a
load/store of fir.type<> which caused hand/asserts to fire in LLVM on
several benchmarks.

See https://llvm.org/docs/Frontend/PerformanceTips.html#avoid-creating-values-of-aggregate-type
