a09000db75 ** Finally DeclareNewGlobalValue is dead!
* Simplify a lot of code because type's cannot be in function symbol tables
* Fix memory leaks in handling of redefined function prototypes
* Don't use SymbolTable directly for stuff that we can go through the Module
  for.
* Fix some minor bugs on obscure testcases like:
      test/Feature/globalredefinition.ll
* Do not create GlobalVariable objects for forward referenced Functions!
* When forward referencing a function in a constant expression, do not create
  a placeholder, add a bunch of references to it, then turn around and
  replaceAllUsesOfWith on it with a new global, deleting the placeholder.
  Instead, when we find the real definition of the global, just use the
  placeholder instead of creating a new object.

This substantially simplifies the asmwriter and should even speed it up on
cases heavy in constantexprs (like C++, Java, MSIL)...

8a32784ad4 * Fairly substantial change. Instead of creating new globalvariables, then
replaceAllUsesWith'ing any forward references, just use the forward
  reference if it exists.

This introduces GetForwardRefForGlobal, which will eventually completely
replace the horrible DeclareNewGlobalValue function.

cb9d6a8f73 Fold setValueNameMergingDuplicates into ParseGlobalVariable, allowing us
to substantially simplify the result.  In particular, we no longer create
GlobalVariables and then immediately destroy them when they are duplciate
definitions.

The real point of this patch though is that it gets us closer to the
DeclareNewGlobalValue calls...

2e2ed2995a Revamp handling of labels. In particular, if we create a forward reference

and creating a new one.  Also, only create at most ONE forward reference
for any block, instead of one for each forward reference.

8c89a0a1fd 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.

8ab406d5bd 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.

75719bf239 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

needs it in order to retain compatibility with setValueName.

16af11d962 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.

026a8ce312 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

25.41s -> 21.72s.
