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.

    Fixes GCC PR 79037.

re PR testsuite/78421 (vect-strided-a-u8-i2-gap.c fails on armeb)

PR testsuite/78421
* lib/target-supports.exp (check_effective_target_vect_hw_misalign):
If the target is ARM return the result of the
check_effective_target_arm_vect_no_misalign proc.
* gcc.dg/vect/vect-strided-a-u8-i2-gap.c: If the target does not
support unaligned vectors then only expect one of the loops to be
unrolled.
