93a57ef458 For PR1146: 
* Add ParamAttrs to InvokeInst class too.
* Make sure all initializes of ParamAttrs in CallInst and InvokeInst are 0
* Destruct the ParamAttrs in Call/Invoke destructors to avoid memory
  leaks. This will change when ParamAttrsList is uniquified but needs to
  be correct until then.

6ee97ee42a Next stage into switch lowering refactoring 
1. Fix some bugs in the jump table lowering threshold
2. Implement much better metric for optimal pivot selection
3. Tune thresholds for different lowering methods
4. Implement shift-and trick for lowering small (<machine word
length) cases with few destinations. Good testcase will follow.

135f2f1261 Chris convinced me that the default size of the SmallVector (2) was too 
small.  Since it doesn't cost much to have 2 more (8 bytes), but not having
them would require a malloc as soon as the third one is needed. Setting
the default to 4 delays the malloc until the 5th parameter attribute.

bcb7b5ca5d Implement more feedback: 
* Allow attributes to be added and removed singly or jointly so that in
  the future something like -pruneh can manipulate them more easily.
* Move functions generally only useful for LLVM internals to the end of
  the accessors list instead of the beginning.

7cf9d12f2e Add DomSet back, and revert the changes to LoopSimplify. Apparently the 
ETForest updating mechanisms don't work as I thought they did.  These changes
will be reapplied once the issue is worked out.

0160bf7114 rearchitect the registration mechanism used by the command line option stuff. 
This dramatically reduce the amount of memory allocated by the commandline stuff
at static init time, changing it to build local data structures when ParseCommandLineOptions
is called.  In a dummy empty program that links some llvm libraries, this reduces
the number of malloc'd bytes from 4864 to 3360 on entry to main.  Most of that
memory is now allocated by non-commandline related stuff.

d0cc2333d1 Switch some vectors to smallvectors. This reduces amount of malloc'd 
memory that occurs before main starts from 5104 to 4864 bytes with a dummy
example app.

d39ae2fa6d Add a helper class (APSInt) which can represent an APInt along with sign 
information.  This is useful when a value does have a sign associated with
it.  This shouldn't be used generally in LLVM for mid-level optimizer stuff.
