GC-parseable element atomic memcpy/memmove
...point. In order to do this we need
to know the base pointers as well. How do we make the base pointers
available in the copy routine? I suggest we add them explicitly as
arguments during lowering.
For example:
__llvm_memcpy_element_unordered_atomic_safepoint_1(
dest_base, dest_derived, src_base, src_derived, length)
It will be up to RS4GC to do the new lowering and prepare the arguments.
RS4GC knows how to compute base pointers for a given derived pointer.
It also already does lowering for deoptimize intrinsics by replacing
an intrinsic call with a symbol call. So there is a precedent here.
