fixes#24673
The problem is that there is no way to distinguish `cint`, `cint`, etc
ctypes with Nim types. So `when T is cint | clong | clonglong:` is true
for types derived from `int`, `int32` and `int64`. In this PR, it fixes
the branch to avoid erros for `Natural`

This pull request adds the `cumproded` function along with its in-place
equivalent, `cumprod`, to the math library. These functions provide
functionality similar to `cumsum` and `cumsummed`, allowing users to
calculate the cumulative sum of elements.
The `cumprod` function computes the cumulative product of elements
in-place, while `cumproded` additionally returns the prod seq.

I have added a new overload of `^` for float exponents.
Is two overloads for `float32` and `float64` better than just one
overload with `SomeFloat` type ?
I guess this would not work with `SomeFloat`, as `pow` is not defined
for `float`.
Another remark. Maybe we should catch exponents with 0.5 and call `sqrt`
instead ?

(cherry picked from commit e9a4d096ab)
The most specific version of `gcd(int,int)` in `std/math` uses bitwise
comparisons from C compilers, which can't be borrowed on the js platform
in the web browser. Conditional compilation here should fix the issue
for this and downstream libraries such as `std/rationals` when compiling
to browser js as the backend.

why ?
- We already have an emit that does the same thing
- The name asm itself is a bit confusing, you might think it's an alias
for asm.js or something else.
- The asm keyword is used differently on different compiler targets (it
makes it inexpressive).
- Does anyone (other than some compiler libraries) use asm instead of
emit ? If yes, it's a bit strange to use asm somewhere and emit
somewhere. By making the asm keyword for js target deprecated, there
would be even less use of the asm keyword for js target, reducing the
amount of confusion.
- New users might accidentally use a non-universal approach via the asm
keyword instead of emit, and then when they learn about asm, try to
figure out what the differences are.

Small fixes/changes
* Move more tests into template main()
* Fix typos
* Add edge case examples for copySign
* Error -> Defect for defects
The distinction between Error and Defect is subjective,
context-dependent and somewhat arbitrary, so when looking at an
exception, it's hard to guess what it is - this happens often when
looking at a `raises` list _without_ opening the corresponding
definition and digging through layers of inheritance.
With the help of a little consistency in naming, it's at least possible
to start disentangling the two error types and the standard lib can set
a good example here.
* Fix classify to test for subnormality.
* Minor fix.
* Modified to maintain existing API.
* Minor change.
* Removed 32-bit case since float is always 64-bit.
