Instead of unconditionally copying all phi node values into temporaries for
all successor blocks, generate code that will determine what successor
block will be called and then copy only those phi node values needed by
the successor block.

This seems to cut down namd execution time from being 8% higher than GCC to
4% higher than GCC.

  - Support added for functions, basic blocks, constant pool, constants,
    registers, and some basic support for globals, all untested

loops.  This optimization is not turned on by default yet, but may be run
with the opt tool's -loop-reduce flag.  There are many FIXMEs listed in the
code that will make it far more applicable to a wide range of code, but you
have to start somewhere :)

This limited version currently triggers on the following tests in the
MultiSource directory:

cfrac: 5 times
anagram: 2 times

Simplify code by simplifying terminators that branch to blocks that start
with an unreachable instruction.

change hacks off 10K of bytecode from perlbmk (.5%) even though the front-end
is not generating them yet and we are not optimizing the resultant code.
This isn't too bad.

like unwind's.

If a function had no return instruction in it, and the result of the inlined
call instruction was used, we would crash.

Pass -single_module option to gcc when linking dynamic libraries for use with bugpoint, so that we can bugpoint multiple .cp files
