I haven't looked closely, but the patch made constructor with priority 0~100 an

I think we should just use a warning to discourage user programs to use 0~100.
Compiler runtime libraries and their tests can freely use 0~100. They know what
they are doing and they are responsible for the interaction with other
constructor users.
```
% gcc -c a.c
a.c:2:1: warning: destructor priorities from 0 to 100 are reserved for the
implementation [-Wprio-ctor-dtor]
2 | int f(void) {
| ^~~
