[ELF] - LTO: Try to be option compatible with the gold plugin. This is relative to PR30720. Previously we ignored all --plugin-opt arguments. Patch adds support for them. Patch does not add any new LTO options, and just implements mapping from --plugin-opt to existent ones. Differential revision: https://reviews.llvm.org/D36227 llvm-svn: 310826

[ELF/LTO] -function-sections/-data-sections are exact options. Also add a test. This fixes r310995 and PR34200. llvm-svn: 310998

[ELF] - Allow set CPU string with -plugin-opt=mcpu=<xxx> Previously we ignored -plugin-opt=mcpu=<xxx> and the only way to set CPU string was to pass -mllvm -mcpu=<xxx> Though clang may pass it with use of plugin options: -plugin-opt=mcpu=x86-64 Since we are trying to be compatible in command line with gold plugin, seems we should support it too.

[ELF] - Re-commit r324322 "Use InitTargetOptionsFromCodeGenFlags/ParseCommandLineOptions for parsing LTO options.". With fix: Keep logic that ignores -plugin-opt=mcpu=x86-64 -plugin-opt=thinlto, add checks for those to testcases. Original commit message: [ELF] - Use InitTargetOptionsFromCodeGenFlags/ParseCommandLineOptions for parsing LTO options. gold plugin uses InitTargetOptionsFromCodeGenFlags + ParseCommandLineOptions for parsing LTO options. Patch do the same change for LLD. Such change helps to avoid parsing/whitelisting LTO plugin options again on linker side, what can help LLD to automatically support new -plugin-opt=xxx options passed.
