This instruction represents integer values, whether they come from literals or calculations, so it the old name is inaccurate. I also plan to rename `BigInt` to `IntLiteral` based on recent discussion and this change aims to avoid confusion stemming from the same name being used for two different things. I'm not renaming `FloatLiteral` because recent discussion suggests we may want distinct `FloatLiteral` versus `FloatValue` representations in SemIR.
