[Bug middle-end/18641] [4.0 Regression] Another ICE caused by reload of a psuedo reg into f0 for a DImode expr

[dje at gcc dot gnu dot org]

For option (2), are you suggesting changing PREFERRED_RELOAD_CLASS from

((GET_CODE (X) == CONST_DOUBLE && GET_MODE_CLASS (GET_MODE (X)) == MODE_FLOAT)
 ? NO_REGS : ...)

to

((GET_CODE (X) == CONST_DOUBLE && reg_classes_intersect_p ((CLASS), FLOAT_REGS))
 ? NO_REGS : ...)

to reload any CONST_DOUBLE into an FPR via memory?
