Sema now properly handles alloc_inferred and alloc_inferred_mut ZIR instructions inside a comptime execution context. In this case it creates Decl objects and points to them with the new `decl_ref_mut` Value Tag. `storePtr` is updated to mutate such Decl types and values. In this case it destroys the old arena and makes a new one, preventing memory growth during comptime code execution. Additionally: * Fix `storePtr` to emit a compile error for a pointer comptime-known to be undefined. * Fix `storePtr` to emit runtime instructions for all the cases that a pointer is comptime-known but does not support comptime dereferencing, such as `@intToPtr` on a hard-coded address, or an extern function. * Fix `ret_coerce` not coercing inside inline function call context.
