Instruction pattern for setting the FPSCR expects the input value to be

This commit fixes the builtin to force the input value into a register.

rs6000: Enable -fasynchronous-unwind-tables by default
To find out where on-entry register values live at any point in a
program, GDB currently tries to parse to parse the executable code.
This does not work very well, for example it gets confused if some
accesses to the stack use the frame pointer (r31) and some use the
stack pointer (r1). A symptom is that backtraces can be cut short.
This patch enables -fasynchronous-unwind-tables by default for rs6000,
which causes us to emit DWARF unwind tables for all functions, solving
these problems.
This not do anything for sub-targets without DWARF, and only for ELF
sub-targets for now.
It increases executable size, but only modestly, and does not change
memory use, only the disk image.

Add missing cases to vect_get_smallest_scalar_type (PR 85286)
In this PR we used WIDEN_SUM_EXPR to vectorise:
short i, y;
int sum;
[...]
for (i = x; i > 0; i--)
sum += y;
with 4 ints and 8 shorts per vector. The problem was that we set
the VF based only on the ints, then calculated the number of vector
copies based on the shorts, giving 4/8. Previously that led to
ncopies==0, but after r249897 we pick it up as an ICE.
In this particular case we could vectorise the reduction by setting
ncopies based on the output type rather than the input type, but it
doesn't seem worth adding a special "optimisation" for such a
pathological case. I think it's really an instance of the more general
problem that we can't vectorise using combinations of (say) 64-bit and
128-bit vectors on targets that support both.

Set insn_last_address in final_1
final_1 already sets insn_current_address for each instruction, making
it possible to use some of the address functions in final.c during
assembly generation. This patch also sets insn_last_address, since
as the comment says, we can treat final as a shorten_branches pass that
does nothing. It's then possible to use insn_current_reference_address
during final as well.
This is needed for the aarch64.md definitions of far_branch to work:
(set (attr "far_branch")
(if_then_else (and (ge (minus (match_dup 2) (pc)) (const_int -
1048576))
(lt (minus (match_dup 2) (pc)) (const_int
1048572)))
(const_int 0)
(const_int 1)))]
This value (tested only during final) uses the difference between
the INSN_ADDRESSES of operand 2 and insn_current_reference_address
to calculate a conservatively-correct estimate of the branch distance.
It takes into account the worst-case gap due to alignment, whereas
a direct comparison of INSN_ADDRESSES would give an unreliable,
optimistic result.

[explow] PR target/85173: validize memory before passing it on to target probe_stack
In this PR the expansion code emits an invalid memory address for the stack probe, which the backend fails to recognise.
The address is created explicitly in anti_adjust_stack_and_probe_stack_clash in explow.c and passed down to gen_probe_stack
without any validation in emit_stack_probe.
This patch fixes the ICE by calling validize_mem on the memory location before passing it down to the target.
Jakub pointed out that we also want to create valid addresses for the probe_stack_address case, so this patch
creates an expand operand and legitimizes it before passing it down to the probe_stack_address expander.
This patch passes bootstrap and testing on arm-none-linux-gnueabihf and aarch64-none-linux-gnu
and ppc64le-redhat-linux on gcc112 in the compile farm.
