* double-int.h (lshift): New overload without precision
and arith argument.
(operator *=, operator +=, operator -=): Move ...
* double-int.c (operator *=, operator +=, operator -=): ... here
and implement more efficiently.
(mul_double_with_sign): Remove.
(lshift_double): Adjust to take unsinged shift argument, push
dispatching code to callers.
(mul_double_wide_with_sign): Add early out for callers that
are not interested in high parts or overflow.
(lshift): New function.
(lshift, rshift, alshift, arshift, llshift, lrshift): Add
dispatch code here.
(lrotate, rrotate): Use logical shifts.
* expr.c (get_inner_reference): Use lshift.
* fixed-value.c (do_fixed_divide): Likewise.
* tree-dfa.c (get_ref_base_and_extent): Likewise.
* tree-ssa-alias.c (indirect_ref_may_alias_decl_p): Likewise.
(indirect_refs_may_alias_p): Likewise.
(stmt_kills_ref_p_1): Likewise.
