[llvm-objcopy] Avoid invalid Sec.Offset after D79229
To avoid undefined behavior caught by -fsanitize=undefined on binary-paddr.test
void SectionWriter::visit(const Section &Sec) {
if (Sec.Type != SHT_NOBITS)
// Sec.Contents is empty while Sec.Offset may be out of bound
llvm::copy(Sec.Contents, Out.getBufferStart() + Sec.Offset);
}
(cherry picked from commit 762fb1c40eea6878c2d6a1f0f1fc7915c8747981)
