Revert "Add missing padding from MemoryChunk struct"
This reverts commitdf0f4fe. It turns out the problem which was causingthe 32-bit ARM and PPC animals to fail was due to a MAXALIGN problem inslab.c. This was fixed byd5ee4db. The padding that was added indf0f4fe would only do anything on machines where uint64 was not alignedto 8 bytes. The 32-bit machines which were failing are not in thatcategory, so revert this commit.Discussion:https://postgr.es/m/3209100.1661787561@sss.pgh.pa.us
