Fangrui Song 242002770b [llvm-objcopy][MachO] Fix symbol order in the symbol table
Only consider isUndefinedSymbol() when the symbol is not local. This
fixes an assert failure when copying the symbol table, if a n_type=0x20
symbol is followed by a n_type=0x64 symbol.

Seiya Nuta b728e53b95 [llvm-objcopy][MachO] Recompute and update offset/size fields in the writer
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.
