[Bug debug/45419] -fcompare-debug failure at -O3

The different types arise when, say, we copyprop a const-unqualified variable
into a MEM_REF that used to reference a const-qualified temp.  The top-level
const qualifications are irrelevant at that point, for we're dealing with
rvalues of pointer types.  I'm experimenting with simply dropping the
TYPE_QUALS test from tree-pretty-print.  This fixed the pt.c -fcompare-debug
problem.  Richard, is there any reason for top-level qualifiers to be relevant
in MEM_REF operands?
