2012-11-29[msan] Transform memcpy and memset to library calls.Evgeniy Stepanov
This was already done for memmove, where it is required for correctness. This change improves performance by avoiding copyingthe same memory twice. Also, the library functions are given __msan_ prefix to prevent instcombine pass from converting them back to intrinsics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168876 91177308-0d34-0410-b5e6-96231b3b80d8
