* ipa-reference.c (mark_load): Use get_base_address.
(mark_store): Likewise.
* tree-ssa-ccp.c (gimplify_and_update_call_from_tree): Avoid
inserting GIMPLE_NOPs into the IL.
* tree-ssa-structalias.c (get_constraint_for_component_ref):
Explicitly strip handled components and indirect references.
* fold-const.c (fold_unary_loc): Do not strip qualifiers when
folding address expressions.
* gimple.c (gimple_ior_addresses_taken_1): Use get_base_address.
* tree-ssa-alias.c (decl_refs_may_alias_p): Do not use
operand_equal_p to compare decls.
(ptr_deref_may_alias_decl_p): Likewise.
* tree-ssa-operands.c (get_asm_expr_operands): Simplify
* tree-ssa-forwprop.c (forward_propagate_into_gimple_cond):
Handle reversed comparison ops.
* tree-sra.c (asm_visit_addr): Use get_base_address.
* ipa-prop.c (visit_store_addr_for_mod_analysis): Use
get_base_address.
* ipa-reference.c (mark_address): Use get_base_address.
