This changes SLP def gathering to not fail due to mismatched
def type but instead demote the def to external. This allows the
new testcase to be vectorized in full (with GCC 10 it is not
vectorized at all and with current trunk we vectorize only the
store). This is important since with BB vectorization being
applied to bigger pieces of code the chance that we mix
internal and external defs for an operand that should end up
treated as external (built from scalars) increases.

* tree-vect-slp.c (vect_get_and_check_slp_defs): For BB
vectorization swap operands only if it helps, demote mismatches to
external.
* gcc.dg/vect/bb-slp-53.c: New testcase.

intrinsics with -O2 (PR97271).
This patch fixes (PR97271) the wrong code-gen for mve scatter store with writeback intrinsics with -O2.
$cat bug.c
void
foo (uint32x4_t * addr, const int offset, int32x4_t value)
{
vstrwq_scatter_base_wb_s32 (addr, 8, value);
}
$ arm-none-eabi-gcc bug.c -S -O2 -march=armv8.1-m.main+mve -mfloat-abi=hard -o -
Without this patch:
...
foo:
vldrw.32 q3, [r0]
vstrw.u32 q0, [q3, #8]! ---> (A)
vldr.64 d4, .L3
vldr.64 d5, .L3+8
vldrw.32 q3, [r0]
vstrw.u32 q2, [q3, #8]! ---> (B)
bx lr
...
With this patch:
...
foo:
vldrw.32 q3, [r0]
vstrw.u32 q0, [q3, #8]! --> (C)
vstrw.32 q3, [r0]
bx lr
...
Without this patch 2 vstrw assembly instructions (A and B) are generated for vstrwq_scatter_base_wb_s32
intrinsic where as fix generates only one vstrw assembly instruction (C).

This enables SLP store group splitting also for loop vectorization.
For the existing testcase gcc.dg/vect/vect-complex-5.c this then
generates much better code, likewise for the PR97428 testcase.
Both of those have a splitting opportunity splitting the group
into two equal (vector-sized) halves, still the patch enables
quite arbitrary splitting since generally the interleaving scheme
results in quite awkward code for even small groups. If any
problems surface with this it's easy to restrict the splitting
to known-good cases.

When hashing a function type the parameter names are ignored.
Therefore, we should not write them into the export data.
Otherwise, minor changes in the order in which we process the
types can cause the export data to change uselessly, leading to
unnecessary rebuilds.

Make the types of the addr and data arguments in the __go_ptrace shim
match the types declared in Go and the types declared by the C ptrace
function, i.e., void*. This avoids a warning about an implicit
int-to-pointer cast on some platforms.

This PR points out that when printing the parameter mapping for a
pointer-to-member-function, the output was truncated:
[with T = void (X::*]
Fixed by printing the abstract declarator for pointers-to-members in
cxx_pretty_printer::type_id. So now we print:
[with T = void (X::*)()]
But when I tried a pointer-to-data-member, I got
[with T = ‘offset_type’ not supported by simple_type_specifier)‘offset_type’ not supported by direct_abstract_declarator]
so had to fix that too so that we now print:
[with T = int X::*]
or
[with T = int (X::*)[5]]
when the type is an array type. Which is what PR85901 was about.
