[llvm-objcopy] Add --strip-all-gnu and change --strip-all
GNU's --strip-all doesn't strip as aggressively as it could in general. Currently llvm-objcopy copies the exact behavoir of GNU's --strip-all. eu-strip is used as a drop in replacement for GNU strip/objcopy in many many places without issue. eu-strip removes non-allocated sections and keeps .gnu.warning* sections. Because --strip-all will likely be the most widely used stripping option we should make --strip-all as aggressive as it can safely be. Since we have evidence from eu-strip that this is a safe option we should allow it. For those that might still have an issue afterwards I've added --strip-all-gnu as an exact drop in replacement for GNU's --strip-all as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@319071 91177308-0d34-0410-b5e6-96231b3b80d8
