This is for more clearly distinct names, and to make it a clearer transition from `BuiltinInst` for name conflicts. `FloatType` is also an instruction, and we have `Carbon::Error` (common/error.h). This avoids affecting tests, although the name is embedded in the builtin test. In `LegacyFloatType`, `Legacy` because I was having trouble coming up with a more appropriate name. I'm not clear this is a `FloatLiteralType` at present, it needs some work to mirror `IntLiteralType`. In `ErrorInst`, the suffix `Inst` was discussed as good and similar to `BuiltinInst` (although I'm trying to get rid of that).
