Prerequisite:

* workaround for bug 45916 (WINEDLLOVERRIDES=msvcr120,msvcp120=n,b)

Tests with x32dbg:

* start 32-bit process in debugger (entry point)
* attaching to running 32-bit process (pause/breakin)
* symbol loading (Wine builtins PDB)
* further debugging (stepping, breakpoints)

Tests with x64dbg:

* start 64-bit process in debugger (entry point)
* attaching to running 64-bit process (pause/breakin)
* symbol loading (Wine builtins PDB)
* further debugging (stepping, breakpoints)

Felt a bit like unwrapping late christmas gift ;-)
