After basic block jump optimization on X86_64, symbol size may need to be adjusted.
Is the `def->value <= OldSize` should be `def->value <= NewSize`?
```CPP
static void fixSymbolsAfterShrinking() {
// ...
if (def->value + def->size > NewSize && def->value <= OldSize &&
def->value + def->size <= OldSize) {
LLVM_DEBUG(llvm::dbgs()
<< "Shrinking symbol " << Sym->getName() << " from "
<< def->size << " to " << def->size - inputSec->bytesDropped
<< " bytes\n");
def->size -= inputSec->bytesDropped;
}
//...
}
```
