bors de17464b14 Auto merge of #65881 - anp:implicit-caller-location, r=eddyb,oli-obk ... Implement #[track_caller] attribute. (RFC 2091 4/N) Implements the `#[track_caller]` attribute in both const and codegen contexts. The const implementation walks up the stack to find the nearest untracked callsite. The codegen implementation adds an implicit argument to tracked function calls, and populates it with either a call to the previously-landed intrinsic or if the caller has `#[track_caller]` with a copy of the location passed to the current function. Also includes a little cleanup and a few comments in the other caller location areas.
