Chris Lattner 4455608818 rewrite DwarfEHPrepare to use SSAUpdater to promote its allocas ... instead of PromoteMemToReg. This allows it to stop using DF and DT, eliminating a computation of DT and DF from clang -O3. Clang is now down to 2 runs of DomFrontier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112457 91177308-0d34-0410-b5e6-96231b3b80d8		2010-08-29 19:54:28 +00:00
