a262a55378 Revamp handling of labels. In particular, if we create a forward reference 
for a basic block, use it when the block is defined instead of deleting it
and creating a new one.  Also, only create at most ONE forward reference
for any block, instead of one for each forward reference.

ed8ebfdac9 Fix typeo and refactor bb productions to make it possible for us to reuse any 
forward reference blocks if they have been created (instead of creating a new
block, replaceAllUsesOfWith, then nuking the placeholder).   This is not yet
implemented.

34682ff049 Now that basic blocks are eagerly inserted into the Function, we can use 
the funciton symbol table to check for conflicts instead of having to
keep a shadow named LocalSymtab.  Totally eliminate LocalSymtab.  Verified
that this did not cause a regression on the testcase for PR107.

83973de5a7 A couple of substantial cleanup fixes: 
1. Split setValueName into two separate functions, one that is only used
     at function scope and doesn't have to deal with duplicates, and one
     that can be used either at global or function scope but that does deal
     with conflicts.  Conflicts were only in there because of the crappy old
     CFE and probably should be entirely eliminated.
  2. Insert BasicBlock's into the parent functions when they are created
     instead of when they are complete.  This effects name lookup (for the
     better), which will be exploited in the next patch.

9a0451787d Provide the correct patch for bug 345. The solution is to add a setTypeName 
function to llvmAsmParser.y and then use it in the one place in the grammar
that needs it. Also had to make Type::setName public because setTypeName
needs it in order to retain compatibility with setValueName.

034a264a99 It turns out that the two dimensional vectors were causing big slowdowns 
in this for programs with lots of types (like the testcase in PR224).
The problem was that the type ID that the outer vector was using was not
very dense (as many types are getting resolved), so the vector is large
and gets reallocated a lot.

Since there are a lot of values in the program (the .ll file is 10M),
each reallocation has to copy the subvectors, which is also quite slow
(this wouldn't be a problem if C++ supported move semantics, but it
doesn't, at least not yet :(

Changing the outer data structure to a map speeds a release build of
llvm-as up from 11.21s to 5.13s on the testcase in PR224.

7eb118e4f7 When resolving upreferences, if multiple uprefs will be resolved to the same 
type at the same time, resolve the upreferences to each other before resolving
it to the outer type.  This shaves off some time from the testcase in PR224, from
25.41s -> 21.72s.

76292e7fcc Instead of searching the entire type graph for a type to determine if it 
contains the type we are looking for, just search the immediately used types.
We can only do this because we keep the "current" type in the nesting level
as we decrement upreferences.

This change speeds up the testcase in PR224 from 50.4s to 22.08s, not
too shabby.

645f8fb4e5 Upreferences are always OpaqueTypes, meaning that it is impossible for a non-abstract
