The negdi2 patterns for ARM and Thumb-2 are duplicated because Thumb-2

Thumb uses a special register allocation order to increase the use of low
registers.  Oddly enough, LR appears before R12, which means that LR must
be saved and restored even if R12 is available.  Swapping R12 and LR means
this simple example now uses R12 as a temporary (just like ARM):

int f(long long a, long long b)
{
  if (a < b) return 1;
  return a + b;
}

Previously users of mulsidi_600 and umulsidi_600 had to take care of
moving the multiplication result into the final destination themselves
(from the MUL64_OUT_REG register).  This commit converts these two
instruction patterns into insn_and_split patterns that now take the
final destination as an extra operand.  The insn_and_split patterns
generate the multiplication using two new multiplication instruction
patterns, then generate the move of the result from the MUL64_OUT_REG
register into the final destination.

This is a clean up commit, there should be no user visible changes
after this commit.

	PR go/78763
    compiler: call determine_types even for constant expressions
    
    We need to call determine_types even for constant expressions, since a
    constant expression may include code like unsafe.Sizeof(0).  Something
    needs to determine the type of the untyped 0, and that should be the
    determine_types pass.
    
    Implementing that triggered a compiler crash on test/const1.go because
    it permitted some erroneous constants to make it all the way to the
    backend.  Catch that case by checking whether we get a constant
    overflow error, and marking the expression invalid if we do.  This is
    a good change in any case, as previously we reported the same constant
    overflow error multiple times, and now we only report it once.

	P0490R0 GB 20: decomposition declaration should commit to tuple
	interpretation early
	* decl.c (get_tuple_size): Make static.  If inst is error_mark_node
	or non-complete type, return NULL_TREE, otherwise if
	lookup_qualified_name fails or doesn't fold into INTEGER_CST, return
	error_mark_node.
	(get_tuple_element_type, get_tuple_decomp_init): Make static.
	(cp_finish_decomp): Pass LOC to get_tuple_size.  If it returns
	error_mark_node, complain and fail.

	* g++.dg/cpp1z/decomp10.C (f1): Adjust expected diagnostics.

Using leaf_function_p in a backend is dangerous as it incorrectly returns
false if it is called while in a sequence (for example during prolog/epilog
generation).  Replace all uses with crtl->is_leaf as this is now initialized
early enough in ira.c.  This typically causes no code generation differences
unless there was a bug due to leaf_function_p returning the wrong value.

    gcc/
        * config/arm/arm.h (TARGET_BACKTRACE): Use crtl->is_leaf.
        * config/arm/arm.c (arm_option_check_internal): Improve comment.
        (thumb_force_lr_save): Use crtl->is_leaf.
        (arm_get_frame_offsets): Remove comment.  Use crtl->is_leaf.
        (thumb_far_jump_used_p): Remove comment.
        (arm_frame_pointer_required): Use crtl->is_leaf.
