[Bug target/27287] [4.1/4.2 Regression] returning constant double

The RTL looks like:

(code_label 34 33 35 2 "" [0 uses])

(note 35 34 0 NOTE_INSN_BASIC_BLOCK)

;; return val
(insn 36 35 37 (set (subreg:DF (reg:DI 136) 0)
        (reg:DF 122 [ val ])) -1 (nil)
    (nil))

(insn 37 36 38 (set (reg:DI 137)
        (reg:DI 136)) -1 (nil)
    (nil))

(insn 38 37 39 (set (reg:DI 120 [ <result> ])
        (reg:DI 137)) -1 (nil)
    (nil))

so this is naked DImode, not SUBREG.  This punning between modes is more than I
plan to try to fix myself.
