Linux kernel source tree

LLVM disassembly support was in disasm.c and addr2line support in srcline.c. Move support out of these files into llvm.[ch] and remove LLVM includes from those files. As disassembly routines can fail, make failure the only option without HAVE_LIBLLVM_SUPPORT. For simplicity's sake, duplicate the read_symbol utility function. The intent with moving LLVM support into a single file is that dynamic support, using dlopen for libllvm, can be added in later patches. This can potentially always succeed or fail, so relying on ifdefs isn't sufficient. Using dlopen is a useful option to minimize the perf tools dependencies and potentially size.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
