Fixes #50243.
Stack allocate the struct we dereference from
unsafe_load()
, when it is a Ptr to an immutable.Also make the same fix to codegen for
unsafe_store!()
on non-isbits immutables.This also fixes a crash caused by illegal instruction.
See: #50243 (comment)
Also adds tests that these don't allocate, and that it doesn't crash.
The tests fail on master, and pass after this commit.
