[clang][Interp] Add explicit dummy descriptors (#68888)
Instead of (ab)using incomplete array types for this, add a 'Dummy' bit
to Descriptor. We need to be able to differentiate between the two when
adding an offset.

3671a69470 [clang][Interp] Call destructors of local variables
This prevents us from leaking memory if the interpretation of byte code
fails midway-throug.

8a58f0d370 [clang][Interp] Handle global composite temporaries
We only did this for primitive temporaries.

Unfortunately, the existing Pointer::toAPValue() won't do here, since
we're expected to set an rvalue on the LifetimeExtendedTemporaryDecl.

865094746e [clang][Interp] Track initialization state of local variables
Use an InlineDescriptor per local variable to track whether locals
have been initialized or not. This way we can support uninitialized
local variables in constexpr functions.

950b70dcc7 [Clang Interpreter] Initial patch for the constexpr interpreter
Summary:
This patch introduces the skeleton of the constexpr interpreter,
capable of evaluating a simple constexpr functions consisting of
if statements. The interpreter is described in more detail in the
RFC. Further patches will add more features.

2c9f83cfab Revert "[Clang Interpreter] Initial patch for the constexpr interpreter"
Breaks BUILD_SHARED_LIBS build, introduces cycles in library dependency
graphs. (clangInterp depends on clangAST which depends on clangInterp)

This reverts r370839, which is an yet another recommit of D64146.
