* tree.c (valid_constant_size_p): New function.
* tree.h (valid_constant_size_p): Declare.
* cfgexpand.c (expand_one_var): Adjust check for too large
variables by using valid_constant_size_p.
* varasm.c (assemble_variable): Likewise.
c/
* c-decl.c (grokdeclarator): Properly check for sizes that
cover more than half of the address-space.
cp/
* decl.c (grokdeclarator): Properly check for sizes that
cover more than half of the address-space.

* fold-const.c (div_if_zero_remainder): sizetypes no longer
sign-extend.
(int_const_binop_1): New worker for int_const_binop with
overflowable parameter. Pass it through
to force_fit_type_double.
(int_const_binop): Wrap around int_const_binop_1 with overflowable
equal to one.
(size_binop_loc): Call int_const_binop_1 with overflowable equal
to minus one, forcing overflow detection for even unsigned types.
(extract_muldiv_1): Remove bogus TYPE_IS_SIZETYPE special-casing.
(fold_binary_loc): Call try_move_mult_to_index with signed offset.
* stor-layout.c (initialize_sizetypes): sizetypes no longer
sign-extend.
(layout_type): For zero-sized arrays ignore overflow on the
size calculations.
* tree-ssa-ccp.c (bit_value_unop_1): Likewise.
(bit_value_binop_1): Likewise.
* tree.c (double_int_to_tree): Likewise.
(double_int_fits_to_tree_p): Likewise.
(force_fit_type_double): Likewise.
(host_integerp): Likewise.
(int_fits_type_p): Likewise.
* varasm.c (output_constructor_regular_field): Sign-extend the
field-offset to cater for negative offsets produced by the Ada frontend.
* omp-low.c (extract_omp_for_data): Convert the loop step to
signed for pointer adjustments.
* g++.dg/tree-ssa/pr19807.C: Adjust.
