[PATCH] D29872: Do not legalize large add with addc/adde, introduce addcarry and do it with uaddo/addcarry

I see, I can do that,  but I'm afraid the test cases will be poor. In this patch the tests cases that exists for ADC are covering the transform, but these tests case can't be leveraged when not using UADDO/ADDCARRY .
