Julius 49e7ef2c09 [Clang]: Diagnose deprecated copy operations also in MSVC compatibility mode 
When running in MSVC compatibility mode, previously no deprecated copy
operation warnings (enabled by -Wdeprecated-copy) were raised. This
restriction was already in place when the deprecated copy warning was
first introduced.

This patch removes said restriction so that deprecated copy warnings, if
enabled, are also raised in MSVC compatibility mode. The reasoning here
being that these warnings are still useful when running in MSVC
compatibility mode and also have to be semi-explicitly enabled in the
first place (using -Wdeprecated-copy, -Wdeprecated or -Wextra).

Dávid Bolvanský abf3ca61e3 [Diagnostics] Restore -Wdeprecated warning when user-declared copy assignment operator is defined as deleted (PR45634) 
Solves https://bugs.llvm.org/show_bug.cgi?id=45634
Be more agressive than GCC with -Wdeprecated-copy. Also provide -W(no-)deprecated-copy-user-provided-copy/dtor options to on/off this behaviour.

Dávid Bolvanský 9353c5dd06 [Diagnostics] Put "deprecated copy" warnings into -Wdeprecated-copy 
Summary:
GCC 9 added -Wdeprecated-copy (as part of -Wextra). This diagnostic is already implemented in Clang too, just hidden under -Wdeprecated (not on by default).
This patch adds -Wdeprecated-copy and makes it compatible with GCC 9+.
This diagnostic is heavily tested in deprecated.cpp, so I added simple tests just to check we warn when new flag/-Wextra is enabled.
