re PR go/79037 (gccgo: Binaries crash with parforsetup: pos is not aligned on m68k)
PR go/79037
compiler, runtime: align gc data for m68k
The current GC requires that the gc data be aligned to at least a 4
byte boundary, because it uses the lower two bits of the address for
flags (see LOOP and PRECISE in runtime/mgc0.c). As the gc data is
stored as a [...]uintptr, that is normally always true. However, on
m68k, that only guarantees 2 byte alignment. Fix it by forcing the
alignment.
The parfor code used by the current GC requires that the parfor data
be aligned to at least an 8 byte boundary. The code in parfor.c
verifies this. This is normally true, as the data uses uint64_t
values, but, again, this must be enforced explicitly on m68k.

rs6000: Small varargs for BE SVR4 (PR61729, PR77850)
The varargs code for SVR4 puts all (integer) arguments in 4-byte slots.
When it then reads an item from there as something not a multiple of 4
bytes, it needs to adjust the address if big endian. We didn't yet do
that.
This fixes the g++.dg/abi/scoped1.C, gcc.dg/compat/scalar-by-value-4,
and gcc.dg/compat/scalar-return-4 testcases.

read from, for big endian.
