[clang][Interp] Diagnose reads from non-const global variables (#71919) 
This fixes a long-standing FIXME item.

Unfortunately it changes the diagnostic output of the tests added in
`cxx23.cpp`, but they were wrong before and are wrong after, so no big
deal.

88abd530ef [clang][Interp] Allow evaluating standalone complex expressions 
We reach visitExpr() when evaluating standalone expressions. However,
the RetValue() code path was unused before, because we never reach it,
even with structs or arrays.

RetValue expects a pointer on the stack it can take apart to return an
APValue, so provide it with one.

[clang][Interp] Fix IntAP(s) to IntAP(s) casts (#69915) 
This was still assert(false)'ed out, it's for casts between two IntAP/IntAPS expressions.
We can't just short-circuit for FromT == ToT because we need to consider the bitwidth when doing the cast.

[clang][Interp] Only evaluate the source array initialization of an ArrayInitLoopExpr once (#68039)

311f725d9a [clang][Interp] Create only globals when initializing a global variable 
For this code:

struct O {
  int &&j;
};

O o1(0);

The generated AST for the initializer of o1 is:

VarDecl 0x62100006ab08 <array.cpp:119:3, col:9> col:5 o1 'O':'O' parenlistinit
`-ExprWithCleanups 0x62100006b250 <col:7, col:9> 'O':'O'
  `-CXXParenListInitExpr 0x62100006b210 <col:7, col:9> 'O':'O'
    `-MaterializeTemporaryExpr 0x62100006b1f0 <col:8> 'int' xvalue
      `-IntegerLiteral 0x62100006abd0 <col:8> 'int' 0

Before this patch, we create a local temporary variable for the
MaterializeTemporaryExpr and destroy it again when destroying the
EvalEmitter we create to interpret the initializer. However, since
O::j is a reference, this reference now points to a local variable
that doesn't exist anymore.

[clang][Interp] Add basic support for _BitInt (#68069)

widths than 128.

[clang][Interp] Add IntegralAP for arbitrary-precision integers (#65844) 
This adds `IntegralAP` backing the two new primtypes `IntAP` (unsigned
arbitrary-precision int) and `IntAPS` (same but signed).

We use this for `int128` support (which isn't available on all host
systems we support AFAIK) and I think we can also use this for `_BitInt`
later.
