[LLVMdev] Question about structure of SymbolTable

To further the confusion on this issue, I am planning on making a change
to the LLVM classes (not the bytecode or asm files) w.r.t types and the
symbol table.  Basically, the symbol table class needs to be cleaned up a
bit, and will end up storing types in a separate map from the global
variables and functions (which will still be a part of the SymbolTable
class though).

The end goal of this is to make the Type class not derive from Value: you
can't use Types in any context where a value makes sense anyway.  For more
information on other planned cleanups, see:

Again, this will not affect the .ll or .bc file formats, only code which
grovels through the symbol table looking for types.  Also note that this
might not happen for another couple of weeks...
