Subject: [PATCH] [CIR] Move the CIR enums off the legacy EnumAttrInfo
hierarchy
MLIR has two enum hierarchies. `EnumAttrInfo` doubles as an `IntegerAttr`
constraint, so every CIR enum had to clear `genSpecializedAttr` to say it did
not want one. `EnumInfo` describes a C++ enum and nothing more.
Derive the CIR bases from `I32Enum`, `I64Enum` and `I32BitEnum`, and widen
`CIR_EnumAttr` to the `EnumInfo` that upstream `EnumAttr` already takes. The
flag no longer exists to clear. `FPClassTestEnum` gets unquoted printing from
`BitEnumBase` rather than overriding `printBitEnumQuoted`, and
`CIR_KnownFuncKind` drops a `parameterPrinter` the generated `operator<<`
now covers, still spelling `#cir.func_identity<"std::find">`.
AMDGPU wraps an `I32Enum` in an `EnumAttr` with this same bracketed format.
Parsing moves to the generated `FieldParser`, whose diagnostic names the
accepted spellings, so two `expected-error` lines change. Generated attribute
code drops 16 KB as 28 inlined parsers collapse into it.
