[ELF] Make MergeInputSection merging aware of output sections Fixes PR38748 mergeSections() calls getOutputSectionName() to get output section names. Two MergeInputSections may be merged even if they are made different by SECTIONS commands. This patch moves mergeSections() after processSectionCommands() and addOrphanSections() to fix the issue. The new pass is renamed to OutputSection::finalizeInputSections(). processSectionCommands() and addorphanSections() are changed to add sections to InputSectionDescription::sectionBases. finalizeInputSections() merges MergeInputSections and migrates `sectionBases` to `sections`. For the -r case, we drop an optimization that tries keeping sh_entsize non-zero. This is for the simplicity of addOrphanSections(). The updated merge-entsize2.s reflects the change.
