7b8e96401c When doing the very-late shift-and address-mode optimization, 
create a new DAG node to represent the new shift to keep the
DAG consistent, even though it'll almost always be folded into
the address.

If a user of the resulting address has multiple uses, the
nodes may get revisited by a later MatchAddress call, in which
case DAG inconsistencies do matter.

This fixes PR2849.

d939f4a347 Don't barf on 32 bit platforms if llvm-gcc is 
not built with 64 bit support.  Since this test
passes without -m64 on x86-32-linux, just remove
the -m64.
