* Don't emit constant pool blocks for methods with empty constant pools!
* Need to implement getelementptr, load, and store for indirection through
arrays and multidim arrays
* BytecodeWriter should use a deque<unsigned char> instead of vector!!!
* Eliminate the method signature from a call instruction. It should look like
this: call int %func(int 2, int %reg118)
* Indirect calls should use the icall instruction
* Rewrite the llvm parser/lexer in http://www.antlr.org when time permits.
They actually do C++. Imagine that.

* Fix DCE to elminate br <c>, %L1, %L1 so that it can optimize the main of
fib.ll better. Currently I have to do this to get best results:
as < fib.ll | opt -inline -sccp -dce -sccp -dce |dis
* fix the constprop br <x> <dst1> <dst1> case. Must handle PHI nodes correctly
* Fix DCE to work better, so that SCCP can show it's true value.
* Implement ADCE
* Fix the const pool printer to print out constants in some sort of "sorted"
order. Then enable TestOptimizer.sh to diff -sccp output. Currently it
doesn't work because the diff fails because of ordering of the constant
pool. :(
* Maybe ConstantPool objects should keep themselves sorted as things are
inserted.
* Enable DoConstantPoolMerging to do trivial DCE of constant values.
* Should provide "castTerminator, castPHI, etc" functions in Instruction, and
similar functions in other classes, that effectively do dynamic casts. This
would allow code like this:

* Finish xvcg output
* pred/succ iterators on basic blocks don't handle switch statements correctly
* Provide a pass that eliminates critical edges from the CFG
* Provide a print pass to print out xvcg format files for vis
* I need to provide an option to the bytecode loader to ignore memory
dependance edges. Instead, the VM would just treat memory operations
(load, store, getfield, putfield, call) as pinned instructions.
* I need to have a way to prevent taking the address of a constant pool
reference. You should only be able to take the address of a variable.
Maybe taking the address of a constant copies it? What about virtual
function tables? Maybe a const pointer would be better...
function tables? Maybe a const pointer would be better... Alternatively,
we could alloca a local variable, copy a constant into it, and use that...
* Need a way to attach bytecode block info at various levels of asm code.
* Need to be able to inflate recursive types. %x = { *%x }, %x = %x ()
* Recognize and save comments in assembly and bytecode format
* Encode line number table in bytecode (like #line), optional table
