  [clang][bytecode] Add test for variadic inherited constructor calls (#225611)

Fixes #158529

Calling a variadic constructor through a `using` declaration used to hit
`assert(false && "Can't get arguments from that expression type")` in
`cleanupAfterFunctionCall`. The call site is a
`CXXInheritedCtorInitExpr`, and the cleanup only knew how to count
variadic arguments from a `CallExpr` or `CXXConstructExpr`. A single
level of `using` crashed the same way, the second level in the
reproducer just adds a frame.

This was fixed as a side effect of #207393, which now takes the variadic
size from the frame instead of the call expression. Adding the
reproducer plus a few value checks (single and double level, mixed
vararg types, inside a constexpr function) so it stays fixed.
