Revert "Issue 18244: std.math generic functions need to have sig constraints"

[MetaLang]

Reverts #6040

This seemingly breaks a fair amount of user code, so we should revert it until we can figure out a less intrusive fix.

Not sure if this is jumping the gun, but better safe than sorry.

OK

[ibuclaw]

Will there be any follow-up action taken?

[MetaLang]

Not sure. @quickfur submitted the fix for 18244 but I don't know if he plans to try a different fix that doesn't break code.

[quickfur]

I'm too busy to work on an alternative fix right now, but the plan is to fix this one way or another somehow. Having unconstrained templates in Phobos is generally not a good idea.

Similar to what we had to do for string constraints.
