[PATCH] fix "32-bit shift" warning in MSVC

This should fix this warning from Visual Studio 2010:
33>..\..\..\llvm-2.8svn-build\lib\MC\MachObjectWriter.cpp(772):
warning C4334: '<<' : result of 32-bit shift implicitly converted to
64 bits (was 64-bit shift intended?)

Index: lib/MC/MachObjectWriter.cpp

fix-32bit-warning.patch (491 Bytes)

The warning was not indicating a bug, but it's ok to fix it in any case, I applied a patch in r111148. Thanks!
