If, for example, GCC is configured such that 'libgomp-plugin-nvptx.so.1'
dynamically links against 'libcuda.so.1', but testing is run on a system where
there is no 'libcuda.so.1', this produces output such as:

PR 95113 revealed that when reasoning about which parameters are dead,
IPA-SRA does not perform the same check related to non-call exceptions

The operands in RTL patterns of MVE vector scatter store intrinsics are wrongly grouped,
because of which few vector loads and stores instructions are wrongly getting optimized
out with -O2.
A new predicate "mve_scatter_memory" is defined in this patch, this predicate returns TRUE on
matching: (mem(reg)) for MVE scatter store intrinsics.
This patch fixes the issue by adding define_expand pattern with "mve_scatter_memory" predicate
and calls the corresponding define_insn by passing register_operand as first argument.
This register_operand is extracted from the operand with "mve_scatter_memory" predicate in
define_expand pattern.

Since it was added in C++11, std::copy_n and std::ranges::copy_n should
do nothing given a negative size, but for random access iterators we add
the size to the iterator, possibly resulting in undefined behaviour.
Also, C++20 clarified that std::copy_n requires the Size type to be
convertible to an integral type. We previously assumed that it could be
directly used in arithmetic expressions, without conversion to an
integral type.
This also fixes a bug in the random_access_iterator_wrapper helper adds
some convenience aliases for using the iterator wrappers.

The following removes the ugly pushing of SLP_TREE_DEF_TYPE to
stmt_infos and instead makes sure to handle invariants fully
in vect_is_simple_use plus adjusting a few places I refrained
from touching when enforcing vector types for them.
It also simplifies building SLP nodes with all external operands
from scalars by not doing that in the parent but instead not
building those from the start. That also gets rid of
vect_update_all_shared_vectypes.
