If you want to try this kind of thing, you should compare it with using
the Boehm gc's free lists, via explicit calls to GC_FREE() and using
`-DINLINE_ALLOC' to inline the GC_MALLOC() allocation code.

The drawback of -DINLINE_ALLOC is a big increase in code size.
The main advantage is that the code is specialized for the allocation size.
We could get the best of both worlds by defining routines
MR_GC_MALLOC_1_WORDS(), MR_GC_MALLOC_2_WORDS(), ..., MR_GC_MALLOC_10_WORDS(),
that would call the inline macro GC_MALLOC_WORDS() to allocate the
specified number of words.  This would probably be a significant win.
