re PR tree-optimization/44831 (internal compiler error: verify_stmts failed when compiling wine)

PR tree-optimization/44831
* tree-ssa-phiprop.c (phiprop_insert_phi): Properly build
a MEM_REF preserving TBAA info of the original dereference.
Dereference the original pointer if the address is not
invariant.
(propagate_with_phi): Fixup type checks wrt MEM_REFs. Require
at least one invariant address that we are going to dereference.
* gcc.c-torture/compile/pr44831.c: New testcase.
* gcc.dg/tree-ssa/pr21463.c: Adjust.
