    compiler: delete lowered constant strings

    If we lower a constant string operation in a Binary_expression,
    delete the strings.  This is safe because constant strings are always
    newly allocated.

    This is a hack to use much less memory when compiling the new
    time/tzdata package, which has a file that contains the sum of over
    13,000 constant strings.  We don't do this for numeric expressions
    because that could cause us to delete an Iota_expression.

    We should have a cleaner approach to memory usage some day.

    Fixes PR go/96450
