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
Signed-off-by: Philip Herron <herron.philip@googlemail.com>
gcc/rust/ChangeLog:
* backend/rust-builtins.cc (BuiltinsContext::setup): add memset builtin to the map
* backend/rust-compile-intrinsic.cc (uninit_handler): implement uninit intrinsic
gcc/testsuite/ChangeLog:
* rust/compile/torture/uninit-intrinsic-1.rs: New test.
