* tests/info.test: Tests 38.* added, exactly testing the tracking

	of location for uplevel scripts.

	* generic/tclCompile.c (TclInitCompileEnv): Reorganized the
	initialization of the #280 location information to match the flow
	in TclEvalObjEx to get more absolute contexts.

	* generic/tclBasic.c (TclEvalObjEx): Moved the pure-list
	optimization out of the eval-direct code path to be done always,
	i.e. even when a compile is requested. This way we do not loose
	the association between #280 location information and the list
	elements, if any.
