c++: Recursive unification with packs and explicit targs [PR94628]
Although, prior to that commit, the test didn't still didn't work:
> lambda-generic-variadic20.ii: In instantiation of 'int fooV(Ts ...) [with Ts = {const char*, int, double, char, float, short int, unsigned int}]':
> lambda-generic-variadic20.ii:16:65: required from here
> lambda-generic-variadic20.ii:6:14: error: expansion pattern 'decltype ('nontype_argument_pack' not supported by dump_expr<expression error>)' contains no parameter packs
I presume the above commit fixed the behaviour in general, but underlying
issues for msp430-elf mean it still doesn't work on that target.
