[LifetimeSafety] Read lifetimebound attribute on implicit 'this' from…
41e231c 
… all redeclarations (#176188)

Fix handling of `lifetimebound` attributes on implicit `this` parameters across function redeclarations.

Previously, the lifetime analysis would miss `lifetimebound` attributes on implicit `this` parameters if they were only present on certain redeclarations of a method. This could lead to false negatives in the lifetime safety analysis. This change ensures that if any redeclaration of a method has the attribute, it will be properly detected and used in the analysis.

I can't seem to work around the crash in the earlier attempt llvm/llvm-project#172146.

Reproducer of the original crash:

```cpp
struct a {
  a &b() [[_Clang::__lifetimebound__]];
};
a &a::b() {}
```
This only crashes with `-target i686-w64-mingw32`. `bin/clang++ -c a.cpp` works fine.
Problematic merging logic:
```cpp
 // If Old has lifetimebound but New doesn't, add it to New.
  if (OldLBAttr && !NewLBAttr) {
    QualType NewMethodType = New->getType();
    QualType AttributedType =
        S.Context.getAttributedType(OldLBAttr, NewMethodType, NewMethodType);
    TypeLocBuilder TLB;
    TLB.pushFullCopy(NewTSI->getTypeLoc());
    AttributedTypeLoc TyLoc = TLB.push<AttributedTypeLoc>(AttributedType); // Crashes.
    TyLoc.setAttr(OldLBAttr);
    New->setType(AttributedType);
    New->setTypeSourceInfo(TLB.getTypeSourceInfo(S.Context, AttributedType));
  }
```

Automerge: [LifetimeSafety] Read lifetimebound attribute on implicit …
642647e 
…'this' from all redeclarations (#176188)

Fix handling of `lifetimebound` attributes on implicit `this` parameters across function redeclarations.

Previously, the lifetime analysis would miss `lifetimebound` attributes on implicit `this` parameters if they were only present on certain redeclarations of a method. This could lead to false negatives in the lifetime safety analysis. This change ensures that if any redeclaration of a method has the attribute, it will be properly detected and used in the analysis.

I can't seem to work around the crash in the earlier attempt llvm/llvm-project#172146.

Reproducer of the original crash:

```cpp
struct a {
  a &b() [[_Clang::__lifetimebound__]];
};
a &a::b() {}
```
This only crashes with `-target i686-w64-mingw32`. `bin/clang++ -c a.cpp` works fine.
Problematic merging logic:
```cpp
 // If Old has lifetimebound but New doesn't, add it to New.
  if (OldLBAttr && !NewLBAttr) {
    QualType NewMethodType = New->getType();
    QualType AttributedType =
        S.Context.getAttributedType(OldLBAttr, NewMethodType, NewMethodType);
    TypeLocBuilder TLB;
    TLB.pushFullCopy(NewTSI->getTypeLoc());
    AttributedTypeLoc TyLoc = TLB.push<AttributedTypeLoc>(AttributedType); // Crashes.
    TyLoc.setAttr(OldLBAttr);
    New->setType(AttributedType);
    New->setTypeSourceInfo(TLB.getTypeSourceInfo(S.Context, AttributedType));
  }
```
