While many programmers may intuitively appreciate the significance of "magic numbers" like −2147483648, Rust is about empowering everyone to build reliable and efficient software! It's a bit more legible to print the constant names (even noisy fully-qualified-paths thereof). The bit-manipulation methods mirror those in `librustc_mir::hair::pattern::_match::all_constructors`; thanks to the immortal Varkor for guidance. Resolves #56393.
