3eeed747ee [llvm-objcopy] Hook up the -V alias to --version, output "GNU strip"
This allows libtool to detect the presence of llvm-strip and use
it with the options --strip-debug and --strip-unneeded.

Also hook up the -V alias for objcopy.

65bac069a6 [llvm-objcopy] Rename --keep to --keep-section.
Summary:
llvm-objcopy/strip support `--keep` (for sections) and `--keep-symbols` (for symbols). For consistency and clarity, rename `--keep` to `--keep-section`.
In fact, for GNU compatability, -K is --keep-symbol, so it's weird that the alias `-K` is not the same as the short-ish `--keep`.

167fb18752 [llvm-objcopy] Support --{enable,disable}-deterministic-archives
Summary: ar and objcopy/strip all support configuring whether archives are written deterministically (timestamps/UIDs/GIDs/etc zero'd). This has been ported to llvm-ar (the U/D modifiers) but not yet to llvm-objcopy/strip.

863ec6dadf [llvm-strip] Support -s alias for --strip-all. Make both strip and objcopy case sensitive to support both -s (--strip-all) and -S (--strip-debug).
Summary:
GNU strip supports both `-s` and `-S` as aliases for `--strip-all` and `--strip-debug`, respectfully.

As part of this, it turns out that strip/objcopy were accepting case insensitive command line args. I'm not sure if there was an explicit reason for this. The only others uses of this are llvm-cvtres/llvm-mt/llvm-lib, which are all tools specific for windows support. Forcing case sensitivity allows both aliases to exist, but seems like a good idea anyway.

And as a surprise test case adjustment, the llvm-strip unit test was running with `-keep=unavailable_symbol`, despite `keep` not be a valid flag for strip. This is because there is a flag `-K` which, when case insensitivity is permitted, allows it to be interpreted as `-K` = `eep=unavailable_symbol` (e.g. to allow `-Kfoo` == `--keep-symbol=foo`).

3b7de9d1bb [llvm-objcopy] Add -F|--target compatibility
Summary:
This change adds support for the GNU --target flag, which sets both --input-target and --output-target.

GNU objcopy doesn't do any checking for whether both --target and --{input,output}-target are used, and so it allows both, e.g. "--target A --output-target B" is equivalent to "--input-target A --output-target B" since the later command line flag would override earlier ones. This may be error prone, so I chose to implement it as an error if both are used. I'm not sure if anyone is actually using both.

bd934ffaab [llvm-objcopy] Factor out CopyConfig
In this diff we move out CopyConfig from llvm-oobjcopy.cpp into a separate header CopyConfig.h
to enable us (in the future) reuse this class in the other implementations of objcopy (for coff, mach-o).
Additionally this enables us to unload the complexity from llvm-objcopy.cpp a little bit.

Test plan: make check-all
