Sirraide d09048a464 [Clang] [C++26] Expansion Statements (P1306R5) (#169680) 
This implements C++26's expansion statements, i.e.
[P1306R5](https://wg21.link/P1306R5).

An expansion statement is implemented using a number of new AST
nodes. Since an expansion statement is a template, we need it to be
a dependent DeclContext, but only nodes that inherit from Decl can
be DeclContexts, for which reason this introduces a CXXExpansionStmtDecl.
This holds a synthesised constant template parameter used as the
expansion index as well as a 'CXXExpansionStmtPattern' and a
'CXXExpansionStmtInstantiation.

These two AST nodes are similar to the semantic vs syntactic form
of an InitListExpr: the 'Pattern' represents an unexpanded expansion
statement, and the resulting AST after expansion is stored in an
'Instantiation'.

Since expansion statements require us to perform template instantiation
*inside* a function without instantiating the rest of a function, I had to
remove a number of assertions in the template instantiation engine (e.g.
the assertion that a function parameter must always have an instantiation 
by the time we encounter a DeclRefExpr to it no longer holds).

For more implementation details, see the corresponding doc comments
in DeclTemplate.h and StmtCXX.h.

There is some follow up work to be done after this lands, which is
tracked in #207776.
