Bug #: 12696
Summary: Attribute bits above 1<<30 are not encoded in bitcode

Patch the encode all ttributes bits in the bitcode
Hi,
define void @f() nonlazybind uwtable
{
ret void;
}
In this trivial example I've uwtable is encoded as (1<<30) while nonlazybind is
(1<<31). When assembling using llvm-as and disassembling using llvm-dis the
code becomes.
define void @f() uwtable {
ret void
}
I think the culprit is
lib/Bitcode/Writer/BitcodeWriter.cpp:186
FauxAttr |= (PAWI.Attrs.Raw() & (0x3FFull << 21)) << 11;
I'm attaching a quick fix
