[Bug translator/2600] New: should optimize away assignments in other contexts

[fche at redhat dot com]

The "dead_assignment_remover" optimization only removes useless assignments from
statement-expressions (top level "a = b" where a is not read anywhere).  It
should do more: look for useless assignments in conditionals (see bug #2599),
array indexes, function parameters, and perhaps even plain nested expression "(x
+ (b = 2) + 5)".
