Constructor invocations such as `APFloat(APFloat::IEEEdouble(), 0.0)` may seem like they accept a FP (floating point) value, but the overload they reach is actually the `integerPart` one, not a `float` or `double` overload (which only exists when `fltSemantics` isn't passed). This may lead to possible loss of data, by the conversion from `float` or `double` to `integerPart`. To prevent future mistakes, a new constructor overload, which accepts any FP value and marked with `delete`, to prevent its usage. Fixes PR34095.
