field into SubclassData in Value. This shrinks GlobalVAlue from 48->40
bytes, Function from 88->76, and GlobalVariable from 76->68. This trims
4640 bytes off my testcase, reading a bc file without materializing any
functions.

object is always constant. As such, evaluate it at compile time instead of storing
it as an ivar in SymbolTableListTraits. This shrinks every SymbolTableListTraits
ilist by a word, shrinking BasicBlock from 44->40 bytes, Function from 96->88 bytes,
and Module from 60->52 bytes.

of two. This shrinkifies Function by 8 bytes (104->96) and Module by 8
bytes (68->60). On a testcase of mine, this reduces the memory used to
read a module header from 565680b to 561024, a little over 4K.

Don't assert everytime an intrinsic name isn't recognized. Instead, make
the assert optional when callin getIntrinsicID(). This allows the assembler
to handle invalid intrinsic names gracefully.

handlers (like the pass list). My previous fix only supported *new* command
line options, not additions to old ones.
This fixes test/Feature/load_module.ll

and Mach-O systems. Additionally, correct the Mach-O logic code to look at
byte 12 not byte 15. Hopefully this fixes the llvm-ld warning on Darwin.

* 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.

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.

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.

* 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.
