df98617b23 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.

5edf210bdf Eliminate questionable syntax for stdin redirection. This probably also speeds things up a bit.

be non-zero.

90008f4bee For PR1319:
Upgrade to new Tcl exec based test framework. This exposes three regressions
in llvm-upgrade:
test/Assembler/2002-08-19-BytecodeReader.llx
test/Assembler/2003-08-21-ConstantExprCast-Fold.llx
test/Assembler/2004-01-11-getelementptrfolding.llx

e3ff5ada8a For PR761:
Remove "target endian/pointersize" or add "target datalayout" to make
the test parse properly or set the datalayout because defaults changes.

For PR645:
Make global names use the @ prefix.

For llvm-upgrade changes:
Fix test cases or completely remove use of llvm-upgrade for test cases
that cannot survive the new renaming or upgrade capabilities.

7e6b4f7a6d For PR1070:
Tweak the RUN: lines of these tests to accommodate the renaming of
variables done by llvm-upgrade. The renaming occurs as a result of avoiding
name collisons for collapsed type planes. Conflicting names have a .u
(unsigned) or .s (signed) suffix added. This patch updates the grep
expression to accommodate the new names.
