Auto merge of #117510 - elichai:patch-3, r=cuviper
Add track_caller to transmute_copy Currently if `size_of::<Src>() < size_of::<Dst>()` you will see the following error: ```rust thread 'test' panicked at /rustc/cc66ad468955717ab92600c770da8c1601a4ff33/library/core/src/mem/mod.rs:1056:5: cannot transmute_copy if Dst is larger than Src ``` This fixes it so it will show the invocation location
