Matthias Braun a451953224 CodeGenModule: Always output wchar_size, check LLVM assumptions. 
Re-commit r303463 now that LLVM is fixed and adjust some lit tests.

llvm::TargetLibraryInfo needs to know the size of wchar_t to work on
functions like `wcslen`. This patch changes clang to always emit the
wchar_size module flag (it would only do so for ARM previously).
This also adds an `assert()` to ensure the LLVM defaults based on the
target triple are in sync with clang.

Matthias Braun 421b63dd70 Revert "CodeGenModule: Always output wchar_size, check LLVM assumptions." 
Let's revert this for now (and with it the assert()) to get the bots
back to green until I have LLVM synced up properly.

This reverts commit r303463.
