gccrs: add uninit intrinsic
Following an investigation from rustc and discussions on zulip the
recommendation was that for uninit we memset to 0x01 which is less likely
to be a null ptr but still an invalid reference.
Fixes #1899

* backend/rust-builtins.cc (BuiltinsContext::setup): add memset builtin to the map
