3ba9a145e9 gcc-plugin: Include additional header for GCC 8
plugin compilation fails on GCC 8:

In file included from gcc-plugins/gcc-common.h:100,
                 from gcc-plugins/ppc64le-plugin.c:1:
/usr/lib/gcc/powerpc64le-linux-gnu/8/plugin/include/attribs.h: In function ‘tree_node* canonicalize_attr_name(tree)’:
/usr/lib/gcc/powerpc64le-linux-gnu/8/plugin/include/attribs.h:118:11: error: ‘get_identifier_with_length’ was not declared in this scope
    return get_identifier_with_length (s + 2, l - 4);
           ^~~~~~~~~~~~~~~~~~~~~~~~~~
/usr/lib/gcc/powerpc64le-linux-gnu/8/plugin/include/attribs.h:118:11: note: suggested alternative: ‘get_attr_min_length’
    return get_identifier_with_length (s + 2, l - 4);
           ^~~~~~~~~~~~~~~~~~~~~~~~~~
           get_attr_min_length
Makefile:34: recipe for target 'gcc-plugins/ppc64le-plugin.so' failed

get_identifier_with_length() is defined under stringpool.h, include this
header file for GCC 8, before including attribs.h

63a94b8323 gcc-plugin: create a ppc64le GCC plugin which inserts nops after local calls
This is in response to an upstream discussion for the following patch:

  https://lkml.kernel.org/r/1508217523-18885-1-git-send-email-kamalesh@linux.vnet.ibm.com

This should hopefully make it a lot easier for the ppc64le kernel module
code to support klp relocations.

The gcc-common.h and gcc-generate-rtl-pass.h header files are copied
from the upstream Linux source tree.
