middle-end/100464 - avoid spurious TREE_ADDRESSABLE in folding debug stmts
canonicalize_constructor_val was setting TREE_ADDRESSABLE on bases
of ADDR_EXPRs but that's futile when we're dealing with CTOR values
in debug stmts. This rips out the code which was added for Java
and should have been an assertion when we didn't have debug stmts.
To not regress g++.dg/tree-ssa/array-temp1.C we have to adjust the
testcase to not look for a no longer applied invalid optimization.
