When compiling package runtime, cmd/compile logically has two copies of package runtime: the actual source files being compiled, and the internal description used for emitting compiler-generated calls. Notably, CL 393715 will cause the compiler's write barrier validation to start recognizing that compiler-generated calls are actually calls to the corresponding functions from the source package. And today, there are some code paths in nowritebarrierrec code paths that actually end up generating code to call panicshift or panicdivide. In preparation, this CL marks those functions as //go:yeswritebarrierrec. We probably want to actually cleanup those code paths to avoid these calls actually (e.g., explicitly convert shift count expressions to an unsigned integer type). But for now, this at least unblocks CL 393715 while preserving the status quo. Updates #51734.
