Hi Martin,

After the backport patch to branch 5, aarch-none-elf fails to build because of
the following ICEs.

gcc/gcc/tree-sra.c: In function ‘tree_node*
replace_removed_params_ssa_names(tree, gimple_statement_base**,
ipa_parm_adjustment_vec)’:
gcc/gcc/tree-sra.c:4609:39: error: cannot convert ‘gimple_statement_base**’ to
‘gimple’ for argument ‘2’ to ‘tree_node* make_ssa_name(tree, gimple)’
gcc/gcc/tree-sra.c: In function ‘bool
ipa_sra_modify_function_body(ipa_parm_adjustment_vec)’:

‘gimple_statement_base**’ for argument ‘2’ to ‘tree_node*

gcc/gcc/tree-sra.c:4772:23: error: cannot convert ‘gimple’ to

The test code also crashes on x86_64 with the current gcc-5-branch and the
gcc-6 development branch.
