As Jakub found, after my recent combine patch at least on x86 problems

This fixes it.

Check array indices in object_address_invariant_in_loop_p (PR 84357)
object_address_invariant_in_loop_p ignored ARRAY_REF indices on
the basis that:
/* Index of the ARRAY_REF was zeroed in analyze_indices, thus we only
need to check the stride and the lower bound of the reference. */
That was true back in 2007 when the code was added:
static void
dr_analyze_indices (struct data_reference *dr, struct loop *nest)
{
[...]
while (handled_component_p (aref))
{
if (TREE_CODE (aref) == ARRAY_REF)
{
op = TREE_OPERAND (aref, 1);
access_fn = analyze_scalar_evolution (loop, op);
access_fn = resolve_mixers (nest, access_fn);
VEC_safe_push (tree, heap, access_fns, access_fn);
TREE_OPERAND (aref, 1) = build_int_cst (TREE_TYPE (op), 0);
}
aref = TREE_OPERAND (aref, 0);
}
but the assignment was removed a few years ago. We were therefore
treating "two->arr[i]" and "three->arr[i]" as loop invariant.

combine: Update links correctly for new I2 (PR84169)
If there is a LOG_LINK between two insns, this means those two insns
can be combined, as far as dataflow is concerned. There never should
be a LOG_LINK between two unrelated insns. If there is one, combine
will try to combine the insns without doing all the needed checks if
the earlier destination is used before the later insn, etc.
Unfortunately we do not update the LOG_LINKs correctly in some cases.
This patch fixes at least some of those cases.
PR rtl-optimization/84169
* combine.c (try_combine): New variable split_i2i3. Set it to true if
we generated a parallel as new i3 and we split that to new i2 and i3
instructions. Handle split_i2i3 similar to swap_i2i3: scan the
LOG_LINKs of i3 to see which of those need to link to i2 now. Link
those to i2, not i1. Partially rewrite this scan code.

compiler: don't export function descriptors for unexported names
They aren't needed, and could potentially cause unlikely symbol name
collisions. Also, the runtime package's reference to main could cause
the runtime package to define main.main..f, which could also be
defined in the main package if it does something like fmt.Print(main).
That will normally work but will fail with a multiple symbol
definition error when using -static-libgo.
