This issues writebarriers for objects added via gc_offsets or by profiling. This may be slower than writebarrier_remember, but we would like it to be more debuggable. Co-authored-by: Max Bernstein <ruby@bernsteinbear.com> Co-authored-by: Stan Lo <stan001212@gmail.com>
When a script has problem with the magic comment encoding, we only display that error. However, if there are other syntax errors in the file, the error linked list could contain multiple items. This lead to an inconsistency in the "size" field of the linked list, and the actual items in the linked list. In other words, the linked list had more than one item, but the size field was one. The error display routine would only allocate `size` items, but iterating the linked list would overrun the array. This commit changes the iterator to compare the current node to the "finish" node in the linked list, no longer assuming the linked list ends with NULL. [Bug #21461]

This lets us ZJIT compiled functions show up in the profiles of, say, perf, or samply. Fix Shopify#634
Use `fixnum_from_isize` instead of `fixnum_from_usize` in `fold_fixnum_bop` to properly handle negative values. Casting negative `i64` to `usize` produces large unsigned values that exceed `RUBY_FIXNUM_MAX`.
