t.p.northover added a comment.
I think it'd be pretty unpopular with the people I know who use freestanding. They're mostly working on microcontrollers and compiling -Oz so the extra code size would be untenable; they also have memcpy implementations anyway because they use it in their own code.
If I was trying to solve this (and I'm also not 100% sure it needs solving), I think I'd instead generate a `linkonce` definition of `memcpy` whenever it's needed and leave CodeGen unmodified.
