Please reconfirm you are willing to:

a) require GCC 9.0 and Clang 9.0
b) not use [[no_unique_address]] in MSVC and clang-cl until Qt 7
c) drop support for any other compilers until they support 
   [[no_unique_address]]

(I think we only have two other supported compilers: Green Hills' and Intel's)
