The problem is that eliminate_local_variables{,_1} calls take_address_of on
ADDR_EXPR etc. in debug stmt expressions.  That affects code generation, so
definitely must not be done.  Either we need to first eliminate local variables
in normal stmts and then do separate processing on debug stmts, where those for
which take_address_of did something would use it, but it wouldn't create new
hash entries and otherwise just reset debug stmts or something, or we need to
reset them right away.
