4803e84704 change ParseMDString and ParseMDNode to take arguments of the right type.
This exposed a raft of other problems, which I'll deal with in subsequent
patches.

bfd6a6f096 switch to TrackingVH instead of WeakVH, since these can never
be RAUW'd and go to null.  This also gets us some sorely lacking
type safety.

e897be280c full asmparser support for blockaddress. We can now do:
$ llvm-as foo.ll -d -disable-output

which reads and prints the .ll file.  BC encoding is the
next project.  Testcase will go in once that works.

eea5412e19 Add support for embedded metadata to LLVM. This introduces two new types of
Constant, MDString and MDNode which can only be used by globals with a name

2db6dc1753 Fix two classes of bugs. First:
validate an invariant so that the asmparser rejects a bad construct
instead of the verifier.  Before:

llvm-as: assembly parsed, but does not verify as correct!
Invalid struct return type!
i64 (%struct.Type*, %struct.Type*)* @foo

after:

llvm-as: t.ll:5:8: functions with 'sret' argument must return void
define i64 @foo(%struct.Type* noalias nocapture sret %agg.result, %struct.Type* nocapture byval %t) nounwind {
       ^


Second, check that void is only used where allowed (in function return types) not in
arbitrary places, fixing PR3747 - Crash in llvm-as with void field in struct.  We
now reject that example with:

$ llvm-as t.ll
llvm-as: t.ll:1:12: struct element can not have void type
%x = type {void}
           ^

f28c74870f Reimplement the old and horrible bison parser for .ll files with a nice
and clean recursive descent parser.

This change has a couple of ramifications:
1. The parser code is about 400 lines shorter (in what we maintain, not
   including what is autogenerated).
2. The code should be significantly faster than the old code because we 
   don't have to work around bison's poor handling of datatypes with 
   ctors/dtors.  This also makes the code much more resistant to memory 
   leaks.
3. We now get caret diagnostics from the .ll parser, woo.
4. The actual diagnostics emited from the parser are completely different
   so a bunch of testcases had to be updated.
5. I now disallow "%ty = type opaque %ty = type i32".  There was no good
   reason to support this, it was just an accident of the old 
   implementation.  I have no reason to think that anyone is actually using
   this.
6. The syntax for sticking a global variable has changed to make it 
   unambiguous.  I don't think anyone is depending on this since only clang
   supports this and it is not solid yet, so I'm not worried about anything
   breaking.
7. This gets rid of the last use of bison, and along with it the .cvs files.
   I'll prune this from the makefiles as a subsequent commit.

There are a few minor cleanups that can be done after this commit (suggestions
welcome!) but this passes dejagnu testing and is ready for its time in the
limelight.
