This reverts commit b39e627be45f847554f11fdac040b6f4da4054ba. The assumed (see comment at <https://gerrit.libreoffice.org/#/c/46769/4/compilerplugins/clang/ plugin.cxx@633>) performance bottleneck of isSamePathname -> getAbsolutePath does show up in Flamegraph inspections of LO builds. But changing (non-member function) isSamePathname to only call getAbsolutePath if (PluginHandlder member function) isLOOLMode is true would need some code reorg, and Online development doesn't seem to make too much actual use of the plugin, so conclusion on IRC was to revert.
