mapcar/maprod: fix stack overflow regression.

The recent refactoring of the mapping functions to use
stack-allocated iterators has a bug. args_decl occurs inside a
loop. But args_decl uses alloca, which doesn't dispose of the
memory when the block scope terminates.

* eval.c (map_common, prod_common): Move the declaration of
args_fun outside of the loop, so that it is allocated just
once. The loop just stuffs fresh sets of values into the
arguments.
