* combine.c (try_combine): Do not worry about MEMs wrapped by USEs.
(expand_compound_operation, expand_field_assignment): Fail if the
bit lengths of an extract operation are out of range.
(make_extraction): Compute wanted_inner_mode based on the position
and length of the extraction. Make it extraction_mode for non-constant
positions, and do not modify offset in that case. When generating a
new MEM, use a mode that can hold the extraction while keeping correct
alignment. Remove code that supported MEMs wrapped by USEs.
(simplify_shift_const_1, force_to_mode) <case USE>: Remove.
