    runtime: factor out bitmap, finalizer code from malloc/mgc · 3965d750
    Russ Cox authored
    The code in mfinal.go is moved from malloc*.go and mgc*.go
    and substantially unchanged.
    
    The code in mbitmap.go is also moved from those files, but
    cleaned up so that it can be called from those files (in most cases
    the code being moved was not already a standalone function).
    I also renamed the constants and wrote comments describing
    the format. The result is a significant cleanup and isolation of
    the bitmap code, but, roughly speaking, it should be treated
    and reviewed as new code.
    
    The other files changed only as much as necessary to support
    this code movement.
    
    This CL does NOT change the semantics of the heap or type
    bitmaps at all, although there are now some obvious opportunities
    to do so in followup CLs.
