compiler: report correct errors for sink methods

    If somebody writes

    func (s []int) _() {}

    we should report an error.  Before this patch we were silently
    accepting this code, because we didn't report any errors about the
    receiver if the method was a sink.

    This patch is unfortunately slightly complex to handle the case of

    func (x int) _() {}

    which we can only detect after define_global_names.

store the bitmap_head within the auto_bitmap

now on the stack, when it isn't its part of some other struct on the
heap instead of being refered to by that struct.  On 64 bit platforms
this will increase the size of such structs by 24 bytes, but its an over
all win since we don't need an 8 byte pointer pointing at the
bitmap_head.  Given that the auto_bitmap owns the bitmap_head anyway we
