Remove some legacy mingw-w64 gcc struct info

Authored by martell on Oct 29 2015, 9:18 AM.



GCC versions starting at 4.8+ conform to standard Windows 64-bit ABI.
Not quite sure if we should keep this to support mingw-w64 and gcc 4.6
Thoughts ?

Also it seems to fix:

Thanks to awson for the tip

Btw, It is a terrible bug.

It is hard to imagine how much C++ code it renders broken on 64-bit mingw-w64 clang. For example, any of hashtable-using code doesn't work etc etc.

Rafael, we don't support pre GCC 4.7 mingw right? They switched to thiscall on 32bit, right? I think we can take a break for x64.

Correct. I we just switched to the 4.7 abi in r197163.

Ohh wow thats dated Dec 12 2013
I assume this would be suitable for 3.7.x then also.
This was originally introduced by @chapuni in rL126186
No test case seems to be present for this so I think this should be good to commit.
@rnk LGTY ?

Sorry, I supposed someone removed it. It was really buggy in past.

From what I can gather it made sense at the time of gcc 4.6 so I don't think anyone is at fault :)
