reload_adjust_reg_for_temp checks only the first hard register for suitability
wrt. NEW_CLASS.
I.e. we check TEST_HARD_REG_BIT (reg_class_contents[(int) new_class], regno) ,
but for a two-hard-reg register we'd also have to check
TEST_HARD_REG_BIT (reg_class_contents[(int) new_class], regno) .

AFAICT the other issues in this PR have been addresssed.

Isn't this really fixed by the TARGET_SECONDARY_RELOAD target hook?
