More fully parse & elaborate "expr in array" construct.

* parse.cxx (parse_array_in): Rewrite.
(parse_symbol_plain): Removed. Update .h to match.
* elaborate.cxx (typeresolution_info::visit_array_in): New function.
(find_array): Tentatively, accept arity=0.
* translate.cxx (c_unparser::c_assign): New functions to eliminate
much ugly duplication. Use throughout.
(visit_symbol): Correct function formal argument search.
(c_tmpcounter*::visit): Add missing recursion in several functions.
* testsuite/*: Add new tests for array-in construct. Add the
first "transok" test.

* translate.cxx: Traverse trees just for common-header generation,
to emit explicit temp variables into context. Switch to explicit
"frame" pointer in generated function/probe bodies. Initialize
locals in function bodies. Rename "test_unparser" to "c_unparser"
throughout.
