Fix bug I introduced with one of my previous changes.
Thanks fly out to Nick for noticing it!  :)

Add some information about the Instruction class and Instruction.def

Add a new BasicBlockPass::doInitialization/Finalization(Function &) pair of
methods that may be useful for BasicBlockPasses.

Make sure to print a message when linking a tool

Compiling with "gmake" should produce less output. The compilation/linking
flags are always the same anyway, who wants to see so much text on the
screen? Compiling with "gmake VERBOSE=1" should produce all the output
you're used to.

Basically it checks for VERBOSE being defined, and if it is, sets VERB
appropriately. VERB is then prepended in a bunch of key places such that
when VERB is "@", the command is not echoed, when VERB is not set to
anything, it's as before.

One thing I could not get rid of is "gmake[1]: Entering directory <blah>",
but running "gmake -s" suppresses it all, and shows just the interesting
stuff.

Now output (when running "gmake -s" will look something like):

Recently changed getelementptr to use 'long' indexes for sequential types
instead of uints.  This adds a translation scheme to be backwards compatible
with old .ll files.
