c8ed902298 little optimization: reuse getPointerToGlobalIfAvailable(CGV) value in emitGlobals() 
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57484 91177308-0d34-0410-b5e6-96231b3b80d8

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.

data-based ones.  Just be conservative when analyzing control-based escapes.
