Add -mcpu to memcpy / memset tests to ensure they behave the same on all hosts / targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100101 91177308-0d34-0410-b5e6-96231b3b80d8

Recreate the size SDNode instead of reusing the old one in the x86 memcpy lowering code; this ensures that the size node has the desired result type. This fixes a regression from r49572 with @llvm.memcpy.i64 on x86-32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49761 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a number of byval / memcpy / memset related codegen issues. 1. x86-64 byval alignment should be max of 8 and alignment of type. Previously the code was not doing what the commit message was saying. 2. Do not use byte repeat move and store operations. These are slow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55139 91177308-0d34-0410-b5e6-96231b3b80d8
