Placeholder for record style GADT declaration
A GADT Declaration is now presented as
CmmCondBranch :: {..} -> CmmNode O C
cml_pred :: CmmExpr
cml_true, cml_false :: !Label
cml_likely :: Maybe Bool
for
CmmCondBranch :: { -- conditional branch
cml_pred :: CmmExpr,
cml_true, cml_false :: ULabel,
cml_likely :: Maybe Bool -- likely result of the conditional,
-- if known
} -> CmmNode O C
