Hi

Seen this for a bunch of programs while trying to run them with installed
dotnet472.

The bug seems to be hidden for several apps as they ship their owm
d3dcompiler_47, but some don`t I found out, and they crash

Something like:
01c2:fixme:d3dcompiler:make_assignment Check for casts in the lhs.
01c2:err:d3dcompiler:compile_shader HLSL shader parsing failed.
01c2:err:ntdll:vDbgPrintExWithPrefix 65: MIL FAILURE: Unexpected HRESULT
0x88760b59 in caller: intermediate rendering error
01c2:err:ntdll:vDbgPrintExWithPrefix 65: MIL FAILURE: Unexpected HRESULT
0x88760b59 in caller: The render thread failed unexpectedly.

Then crash

Example: Slackinstaller.exe:

winetricks dotnet452 win7 corefonts, then start installer with builtin
d3dcomiler_47 works fine.

However
winetricks dotnet472 win7 corefonts, then start installer with builtin
d3dcomiler_47 --> crash

(Note: for Slackinstller one also needs Staging-patches for bug 40613)
