PR middle-end/41047
* tree-ssa-ccp.c (ccp_fold): When folding pointer additions
use the constant pointer type.
* gimplify.c (canonicalize_addr_expr): Canonicalize independent
of CV qualifiers on the target pointer type.
* tree-ssa.c (useless_type_conversion_p): Move incomplete pointer
conversion check before restrict check.
* gcc.dg/tree-ssa/ssa-ccp-27.c: New testcase.
