Alexander Shaposhnikov c54959c00d Introduce llvm-install-name-tool
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.

Differential revision: https://reviews.llvm.org/D69146

Test plan: make check-all

Fangrui Song 28a5dc7fc5 [llvm-objcopy][MachO] Implement --redefine-sym and --redefine-syms
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.

Seiya Nuta 552bcb854c Recommit "[llvm-objcopy][MachO] Support load commands used in executables/shared libraries"
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.
