Aleksandr Platonov 5a42c90b77 [clang] Make variables of undeduced types to have dependent alignment 
Without this patch `VarDecl::hasDependent()` checks only undeduced auto types, so can give false negatives result for other undeduced types.
This lead to crashes in sequence `!VarDecl::hasDepentent()` => `getDeclAlign()`.

It seems this problem appeared since D105380

Paul Robinson d30e2eefc3 Add a "maximum TLS alignment" characteristic to the target info, so it 
can be different from the normal variable maximum.
Add an error diagnostic for when TLS variables exceed maximum TLS alignment.
Currenty only PS4 sets an explicit maximum TLS alignment.
