    • [AArch64] Remove SVE XFAILs · ba261579 
      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).

    • compiler: update iota handling, fix using iota in array length · 5dfb4d0f 
          
    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.

    • compiler: in range, evaluate array if it has receives or calls · 964c809f 
          
    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 :=.

    While we're here fix the value returned by the type method of a

    any difference anywhere since we lower this to a runtime call before
