This reduces the size of the instruction class by 4 bytes, and means that
isa<CallInst>(V) (for example) only needs to do one load from memory instead
of two.

symbols with. Therefore, if you do not use struct/class consistently, you can
get LINK ERRORS. grr.
This fixes the link errors for libsupport and vmcore.

all dynamically allocated LLVM values 4 bytes smaller, eliminate some vtables, and
make Value's destructor faster.
This makes Function derive from Annotation now because it is the only core LLVM
class that still has an annotation stuck onto it: MachineFunction.
MachineFunction is obviously horrible and gross (like most other annotations), but
will be the subject of refactorings later in the future. Besides many fewer
Function objects are dynamically allocated that instructions blocks, constants,
types, etc... :)

this list (except use_size()) are constant time. Before the killUse method
(used whenever something stopped using a value) was linear time, and thus
very very slow for large programs.
This speeds GCCAS up _substantially_ on large programs: almost 2x for 176.gcc:
176.gcc: 77.07s -> 37.38s
177.mesa: 7.59s -> 5.57s
252.eon: 21.02s -> 19.52s (*)
253.perlbmk: 11.40s -> 13.05s
254.gap: 7.25s -> 7.42s
252.eon would speed up a whole lot more, but optimization time is being
dominated by the inlining pass, which needs to be fixed.

significantly more complete. Instead, just make DerivedType's AbstractTypeUser's,
and make Value contain a PATypeHolder. This will also be more efficient in the
future.

* Add top level virtual print function, disallows instantiating Value's
directly.
* Provide operator<< for values here, instead of in Assembly/Writer.h
llvm-svn: 2168
* ConstPoolPointerReference now represents a pointer to a GlobalValue
* Methods name references are now explicit pointers to methods
* Rename Value::GlobalVal to Value::GlobalVariableVal to avoid confusion
llvm-svn: 703
* ValueHolder became a 3 argument template. This allows for BasicBlock to
use the value holder arg as a typesafe parent pointer.
* SymTabValue no longer inherits from Value
* Method does not inherit from only SymTabValue. Now it inherits from both
STV & Value.
* Module does not inherit from only SymTabValue. Now it inherits from both
STV & Value.
* Updated the SymTabValue.h file to reference SymTabValue instead of STDef
in several places
* Added isArraySelector & isStructSelector to GetElementPtr instruction
