"dict" was added in Tcl 8.5, but until a couple of weeks ago the
testsuite had worked with 8.4.

This patch uses arrays instead, like we do for the caching in
target-supports.exp.  It is a bit uglier than using dicts was,
but hopefully not too bad...

These tests started passing after r257293, which had the side-effect
of renumbering the SSA names and leaving the COND_EXPRs in their
natural order.

This does show a deeper underlying issue that code generation is too
sensitive to internal things like SSA_NAME versions, but it no longer
affects these particular tests (for now).

    CL 71750 changed the definition of how iota works.  This patch updates
    gccgo for the new definition.
    
    We've been mishandling iota appearing in a type that appears in a
    const expression, as in `c = len([iota]int{})`.  Correct that by copying
    type expressions when we copy an expression.  For simplicity only copy
    when it can change the size of a type, as that is the only case where
    iota in a type can affect the value of a constant (I think).  This is
    still a bunch of changes, but almost all boilerplate.

    The last change was incomplete, in that it did not evaluate the array
    argument in some cases where it had to be evaluated.  This reuses the
    existing code for checking whether len/cap is constant.
    
    Also clean up the use of _ as the second variable in a for/range,
    which was previously inconsistent depending on whether the statement
    used = or :=.
