Eli Friedman	55d484802f	Skip extra copy from aggregate where it isn't necessary; rdar://problem/8139919 . This shouldn't make much of a difference at -O3, but should substantially reduce the number of generated memcpy's at -O0. Originally r130717, but was backed out due to an ObjC regression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@132102 91177308-0d34-0410-b5e6-96231b3b80d8	2011-05-26 00:10:27 +00:00
