compiler: update iota handling, fix using iota in array length

    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.

net: declare lib_getaddrinfo as returning int32

    Otherwise on a 64-bit system we will read the 32-bit value as a 64-bit
    value.  Since getaddrinfo returns negative numbers as error values,
    these will be interpreted as numbers like 0xfffffffe rather than -2,
    and the comparisons with values like syscall.EAI_NONAME will fail.

    Fixes golang/go#23645
