Optimizing the rest of bool's Ord implementation

After coming across issue rust-lang#66780, I realized that the other functions provided by Ord (`min`, `max`, and `clamp`) were similarly inefficient for bool. This change provides implementations for them in terms of boolean operators, resulting in much simpler assembly and faster code.
Fixes issue rust-lang#114653

`max` assembly before:
```assembly
example::max:
        mov     eax, edi
        mov     ecx, eax
        neg     cl
        mov     edx, esi
        not     dl
        cmp     dl, cl
        cmove   eax, esi
        ret
```
`max` assembly after:
```assembly
example::max:
        mov     eax, edi
        or      eax, esi
        ret
```
`clamp` assembly before:
```assembly
example::clamp:
        mov     eax, esi
        sub     al, dl
        inc     al
        cmp     al, 2
        jae     .LBB1_1
        mov     eax, edi
        sub     al, sil
        movzx   ecx, dil
        sub     dil, dl
        cmp     dil, 1
        movzx   edx, dl
        cmovne  edx, ecx
        cmp     al, -1
        movzx   eax, sil
        cmovne  eax, edx
        ret
.LBB1_1:
        ; identical assert! code
```
`clamp` assembly after:
```assembly
example::clamp:
        test    edx, edx
        jne     .LBB1_2
        test    sil, sil
        jne     .LBB1_3
.LBB1_2:
        or      dil, sil
        and     dil, dl
        mov     eax, edi
        ret
.LBB1_3:
        ; identical assert! code
```
