Patch to make compile with LLVM 7

Build of d3682766f66b69ab636a2b9ca74db48fab68e024 using the attached patch to make it compile with LLVM 7. When loading X, it crashes with the backtrace:

%rcx is 0x3000000002

Buffer is:
$5 = {Data = 0x3000000002 <error: Cannot access memory at address 0x3000000002>, Length = 140726874677440}

0x7ffd87602020: 0x3000000002    0x7ffd876020c0

Unfortunately, frame 15 (the first SWR one) is not debuggable due to the inlining of StringRef inside the function and I can't find "Gen_SWR_VERTEX_BUFFER_STATE" in the Mesa sources.

Hi Thiago,

Thanks for the details and patch on this. Can you describe what compile error you're receiving with LLVM 7? And what configure flags you're using? We have an upcoming patch to support LLVM 7, but it has different fixes compared to the patch provided.

That's because I uploaded the wrong patch...

I created https://bugs.freedesktop.org/show_bug.cgi?id=108310 to track the need for patch.
