[AMDGPU] Implement CFI for CSR spills

Introduce new SPILL pseudos to allow CFI to be generated for only CSR
spills, and to make ISA-instruction-level accurate information.

Other targets either generate slightly incorrect information or rely on
conventions for how spills are placed within the entry block. The
approach in this change produces larger unwind tables, with the
increased size being spent on additional DW_CFA_advance_location
instructions needed to describe the unwinding accurately.

[LSV] Add SCEV unsigned range safety check for zero-extend (#197599)

Add a fourth safety check in the `getConstantOffsetComplexAddrs`, that
uses SCEV's unsigned range to prove that the addition doesn't cause
unsigned overflow. This is needed for the case, where the KnownBits
analysis can't prove the safety, but SCEV has tighter range information.

The new check allows to vectorize more cases, where the offset is
zero-extended from a smaller type.

[clang][NFC] Disentangle `MacroState` from `Preprocessor`

`Preprocessor` contains a map of `IdentifierInfo` to `MacroState`; this is reasonable -- the macro state is part of the overall preprocessor state. `MacroState` depends on `Preprocessor`; this is less reasonable and means that to understand `MacroState` you must first understand `Preprocessor`, but to understand `Preprocessor` you must first understand `MacroState`.

Move `MacroState` to its own file. This pulls along `FullModuleMacroInfo` since a `MacroState` is either a `MacroDirective` or a `FullModuleMacroInfo`.

Replace all `Preprocessor` parameters with only the components of `Preprocessor` that we actually need. This gives us a simpler layering where `Preprocessor` code knows about `MacroState` but `MacroState` code does not know about `Preprocessor`.

`updateModuleMacroInfo` used to be a private member function of `Preprocessor`, but its purpose is to manage `MacroState`. Instead have `MacroState` use it as an implementation detail function.

Add a new type, `PPReferences`, to bundle up references to state that `MacroState` needs as read-only other than the `IdentifierInfo` (since that's conceptually a different kind of thing).

This change also required changing `MacroInfo::isIdenticalTo` to accept the useful components of `Preprocessor` rather than the whole `Preprocessor`.

[lldb] Use os_unfair_lock for the string pool on Darwin (#197851)

The ConstString pool guards each shard with a SmartRWMutex<false>, which
on Darwin maps to pthread_rwlock and incurs heavy syscall overhead under
contention. os_unfair_lock is a userspace fast path that's significantly
faster for the write path and roughly on par for reads, but it's
exclusive-only and not available off Apple platforms.

On a 32-thread machine, hyperfine reports the benchmark unit test binary
running 4.07x faster (365.6 ms +/- 3.9 ms -> 89.8 ms +/- 5.1 ms), with
system time dropping from 4.35 s to 0.39 s as the kernel pthread_rwlock
path is replaced by the userspace fast path.

[lldb] Assert that CommandObject::DoExecute sets a return status (#197796)

Change the default value of CommandReturnObject::m_status from

check in CommandObjectParsed::Execute and CommandObjectRaw::Execute that
asserts the status is no longer Invalid after DoExecute returns.

This catches commands that forget to call SetStatus on a success or
failure path. Succeeded() still returns true when the status is Invalid
(0 sorts below eReturnStatusSuccessContinuingResult), so helpers that
read result.Succeeded() as a precondition before any explicit SetStatus
(e.g. StopProcessIfNecessary) continue to work.

This is a re-land of #196589.

LLVM/project 6be939eclang/lib/CIR/CodeGen CIRGenFunction.cpp CIRGenCall.cpp, clang/test/CIR/CodeGen cxx23-explicit-object-member.cpp

[CIR] Honor explicit-object parameter in CXX method arrangement

CIRGen's CXX method-arrangement and prolog paths use `md->isInstance()` to decide whether to prepend a CXXABI-supplied `this` to the parameter list.  `isInstance()` is positive for *any* non-static member, including C++23 explicit-object member functions (P0847R7, `void f(this Self&&)`), where the explicit object parameter takes the place of the implicit `this` at the AST level and appears as the first parameter of the `FunctionProtoType`.

For these methods the existing path produces a `CIRGenFunctionInfo` with one more argument than `convertType(fd->getType())` gives the matching `cir.func` type, so `setCIRFunctionAttributes` runs `setArgAttrs` off the end of the cir.func arg list and crashes with `"invalid argument number"`.  The same off-by-one shows up on the prolog side, where `buildFunctionArgList` prepends a `this` `ParmVarDecl` that doesn't actually exist and `emitInstanceFunctionProlog` sets up `CXXThisValue` from a cir.func argument that is really the explicit-object parameter.  The crash hits 29 tests in the libcxx `std/utilities/format/**` and `std/containers/**/format/**` subtrees on the current four-fix integration baseline, plus `std/utilities/function.objects/func.bind.partial/bind_front.nttp.pass.cpp`.

Switch three sites in `CIRGenCall.cpp` and `CIRGenFunction.cpp` to the positive predicate `isImplicitObjectMemberFunction()`, matching how classic CodeGen distinguishes the two cases in `CGCall.cpp`.  Explicit-object members now flow through `arrangeFreeFunctionType`, are entered into `localDeclMap` as regular parameters, and lower to the same LLVM IR that classic CodeGen produces for the same source.

New `cxx23-explicit-object-member.cpp` test (CIR + a shared `LLVM` prefix that covers both the CIR-to-LLVM and OGCG runs) covers `operator()(this Self const& self, int)` with and without `self`-side member access, a `[](this auto const&, int){...}` lambda invocation, and a control implicit-`this` instance method whose CIR signature still begins with `!cir.ptr<!rec_*>`.
