  Fixed flag names for dumping CFG.

  Added flags to functor parameters to control hte behavior of the
  algorithm.  The reverseDirection flag is currently a nop.

  Added functor to compute block and edge frequencies from edge
  probabilities.

Tested the jump chain elimination on all architectures (except the
hppa).  This is on by default right now and is profitable for the
alpha and x86, however, it may not be profitable for the sparc and ppc
when compiling the compiler.

The gc test will typically jump to a label at the end of the cluster,
where there is another jump to an external cluster containing the actual
code to invoke gc. This is to allow factoring of common gc invocation
sequences. That is to say, we generate:

	f:
	   testgc
	   ja	L1	% jump if above to L1

	L1:
	   jmp L2


After jump chain elimination the 'ja L1' instructions is converted to
'ja L2'. On the sparc and ppc, many of the 'ja L2' instructions may end
up being implemented in their long form (if L2 is far away) using:

	jbe	L3	% jump if below or equal to L3
        jmp 	L2
     L3:
	...


For large compilation units L2  may be far away.

implemented generic Controls module and used it for
all compiler flags/tuneable knobs/...;
more command-line options accepted (for setting the above controls);
some minor bug fixes
