[Mesa-dev] [PATCH] swr/rast: Fix WriteBitcodeToFile usage with llvm-7.0.

[Vinson Lee]

Fix build error after llvm-7.0svn r325155 ("Pass a reference to a module
to the bitcode writer.").

  CXX      rasterizer/jitter/libmesaswr_la-JitManager.lo
rasterizer/jitter/JitManager.cpp:548:30: error: reference to type 'const llvm::Module' could not bind to an lvalue of type 'const llvm::Module *'
    llvm::WriteBitcodeToFile(M, bitcodeStream);
                             ^
