diagnostics:

Chris Lattner c38e99547e add checking intentionally elided for vfcmp/vicmp since they should really
just be removed.  However, this fixes PR3281:crash04.ll, diagnosing it with:

lvm-as: crash04.ll:2:13: vfcmp requires vector floating point operands
  vfcmp uno double* undef, undef

Chris Lattner 998fa0a2a2 fix PR3281:accepted0[02].ll: represent empty arrays distinctly, and
diagnose attempts to initialize non-empty arrays with them.  This 
produces:

@"o" = global [5 x double] []
                           ^

Chris Lattner ad6f3355a7 Refactor some parser interfaces to fix PR3278 and a FIXME:
ParseAssemblyString with a specified module would not parse
into the module, it would create and return a new one.

Chris Lattner ac161bff07 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.
