pkg/compiler: fix incorrect alignment calculation for padding
We assumed that for ConstType alignment is equal to size,
which is perfectly reasonable for normal int8/16/32/64/ptr.
However, padding is also represented by ConstType of arbitrary size,
so if we added 157 bytes of padding that becomes alignment of
the padding field and as the result of the whole struct.
This affects very few structs, but quite radically and quite
important structs.
Discovered thanks to syz-check.
Update #590
