Florian Hahn 1ddb3a369f [LangRef] Adjust guarantee for llvm.memcpy to also allow equal arguments. ...

This adjusts the description of `llvm.memcpy` to also allow operands
to be equal. This is in line with what Clang currently expects.

This change is intended to be temporary and followed by re-introduce
a variant with the non-overlapping guarantee for cases where we can
actually ensure that property in the front-end.
