information and Loop info will not have to be recomputed after this runs.

dd74dc44b6 - Fix a really nasty bug in the bytecode reader that caused it to fail 
reading bytecode files with > 255 types in them, but only when optimization
    is enabled.  This was caused by GCC shrinking an enum to a single byte
    instead of a whole word.

a2c2d8af59 Wow, for some reason, when reading bytecode from stdin, we were only reading 
4 bytes at a time.  Change this to read blocks of 4k

dfc8fbf16b - Two minor improvements to the MachineInstr class to reduce footprint and 
overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a
    bitvector.  Sped up LLC a little less than 10% in a debug build!

296c58a00c - Make sure to only keep track of mappings that the TD pass may need in the 
future.  This prevents having spurious map entries to nodes that we really
    don't care about.  This allows us to reenable the DeadNodeElim, which was
    disabled.

4410178282 - Add "ResolvingCaller" to the CallSite record. This keeps track of which 
function was finally able to resolve the function call.  Adding this allows
    the TD pass to actually work right!
  - Temporarily disable dead node pruning.  This will be reenabled soon.

1276c50e7b As it turns out, we don't need a fully generic mapping copy ctor, we just need 
something that maps through a std::map.  Since this simplified the client and
implementation code, do so now.

8929f75913 Don't create a new node for every reference to a global. This caused a huge 
node explosion that doesn't help anything at all.  In previous versions of
the representation this DID help, but not anymore.

2914391ab6 - Make DSCallSite not inherit from std::vector. Renamed methods slightly. 
Make copy ctor have two versions to avoid dealing with conditional template
    argument.  DSCallSite ctor now takes all arguments instead of taking one
    and being populated later.

c02c96c3de Added a first-class representation for each call site that can be 
used in the DS graphs.  Essentially, what was vector<DSNodeHandle>
before is now a DSCallSite with the same vector, plus pointers to the
CallInst and the caller Function.  The special-purpose class
BUDataStructure::CallSite is no longer needed.

5028142e9a * First try at implementing TD pass this does not merge global nodes yet, 
among other things.
  * Significant rewrite of TD pass to avoid potentially N^2 algorithms if
    possible.  It is still not complete, but at least it's checked in now.
