memcpy to match the alignment of the destination. It isn't necessary for making loads and stores handled like the SSE loadu/storeu intrinsics, and it was causing a performance regression in MultiSource/Applications/JM/lencod. The problem appears to have been a memcpy that copies from some highly aligned array into an alloca; the alloca was then being assigned a large alignment, which required codegen to perform dynamic stack-pointer re-alignment, which forced the enclosing function to have a frame pointer, which led to increased spilling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65289 91177308-0d34-0410-b5e6-96231b3b80d8
