[ Upstream commit b77afa1f810f37bd8a36cb1318178dfe2d7af6b6 ]
Fix die_is_func_instance() to find range-only function instance.
In some case, a function instance can be made without any low PC or
entry PC, but only with address ranges by optimization. (e.g. cold text
partially in "text.unlikely" section) To find such function instance, we
have to check the range attribute too.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
