alignment: set alignment on structs

Browse Source 
This uses an alternate idea for setting the structure alignments. Lets
see if this silents the ARM builder cast alignment issues.

GSlice (which is what is used for GObjects) guarantees a 2-pointer size
allocation, which means we can be ensured that the alignment is at least
8 bytes.
