These were copied as part of the original design from the ELF
backend, but aren't necessary at the moment.

Martin Storsjo d1cc64fe12 [llvm-objcopy] [COFF] Fix writing object files without symbols/string table 
Previously, this was broken - by setting PointerToSymbolTable to zero
but still actually writing the string table length, the object file
header was corrupted.

Martin Storsjo 14cfa9ae2e [llvm-objcopy] [COFF] Avoid memcpy() with null parameters in more places. NFC. 
This fixes all cases of errors in asan+ubsan builds.

Also use std::copy instead of if+memcpy in the previously updated spot,
for consistency.

Martin Storsjo 02e96dd039 [llvm-objcopy] [COFF] Don't call memcpy() with a null argument. NFC. 
It is invalid to call memcpy with a null pointer, even if the size
is zero.

This should fix the sanitizer buildbot.
