In this case, we are creating an x86_fp80 slice for a union from C where the padding bytes may contain real data. An x86_fp80 alloca is 16 bytes, and that's just fine. We can't, however, use regular loads and stores to access the slice, because the store size is only 10 bytes / 80 bits. Instead, use memcpy and memset. Fixes PR18726.
