Reducing the assumed alignment of struct varlena means that the compiler
is also licensed to put a local variable declared that way at an unalignedaddress. Which will not work if the variable is then manipulated withSET_VARSIZE or other macros that assume alignment. So the previous patchis not an unalloyed good, but on balance I think it's still a win, sincewe have very few places that do that sort of thing. Fix the one place intuptoaster.c that does it. Per buildfarm results from gypsy_moth(I'm a bit surprised that only one machine showed a failure).
