In this diff we change the storage of a section to unique_ptr.
This refactoring was factored out from D71647.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
This diff adds a new "driver" for llvm-objcopy
which is supposed to emulate the behavior of install-name-tool.
This is a recommit of b5913e6 with ubsan, test dependencies issues fixed.

Similar to D46029 (ELF) and D70036 (COFF), but for MachO.
Note, when --strip-symbol (not implemented for MachO) is also specified,
--redefine-sym executes before --strip-symbol.

Fixes PR43181. This option was recently added to GNU objcopy (binutils
PR24942).
`llvm-objcopy -I binary -O elf64-x86-64 --set-section-alignment .data=8` can set the alignment of .data.

Summary:
This patch implements copying some load commands that appear in executables/shared libraries such as the indirect symbol table.
I don't add tests intentionally because this patch is incomplete: we need a layout algorithm for executables/shared libraries. I'll submit it as a separate patch with tests.

Summary:
Recompute and update offset/size fields so that we can implement llvm-objcopy options like --only-section.
This patch is the first step and focuses on supporting load commands that covered by existing tests: executable files and
dynamic libraries are not supported.

Summary:
It is better to print an error message instead of silently ignoring unsupported options.
As mentioned in https://reviews.llvm.org/D57045, this is not the best solution and we should print which flag is not supported at some time.
