8781203372 chore: rename misleading function
`charToHex` is an auxiliary function used at `Char.quoteCore` for
converting ASCII control characters into `\x` notation.
Its name was misleading.

c46ef56ac7 perf: avoid blowup at deriving Repr
The fix is not perfect. I just avoided inlining in some builtin `Repr` instances.
The actual problem is at `ElimDeadBranches.lean`.

4c707d3b3c feat: use binop% to elaborate %-applications
Motivation: make sure the behavior is consistent with other arithmetic
operators.

This commit also removes the instance
```
instance : HMod (Fin n) Nat (Fin n) where
  hMod := Fin.modn
```
because we have a coercion from `Fin n` to `Nat`.
Thus, given `a : Fin n` and `b : Nat`, `a % b` is ambiguous.

34dc2572f3 fix: make sure OfScientific Float instance is never unfolded during type class resolution
This commit fixes issue reported at
https://leanprover.zulipchat.com/#narrow/stream/270676-lean4/topic/deterministic.20timeout/near/287654818

Type class resolution was diverging when trying to synthesize
```lean
 HSub (optParam Float 0.0) (optParam Float 1.0) ?m.472
```
and Lean was diverging while unfolding
```lean
 instance : OfScientific Float where
   ofScientific m s e :=
     if s then
       let s := 64 - m.log2 -- ensure we have 64 bits of mantissa left after division
       let m := (m <<< (3 * e + s)) / 5^e
       Float.ofBinaryScientific m (-4 * e - s)
     else
       Float.ofBinaryScientific (m * 5^e) e
```
was being unfolded.

Anothe potential solution for the problem above is to erase the
`optParam` annotations before performing type class resolution.
