Rewrite test/Linker tests to use FileCheck instead of grep. Some translations here are not 1x1 because there are grep\|grep chains that are non-trivial to implement in terms of FileCheck features. I made an effort for the tests to remain as similar as possible; do let me know if you notice anything fishy. The good news are that some buggy tests were fixed (grep \| not grep - a bug waiting to happen). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179102 91177308-0d34-0410-b5e6-96231b3b80d8 2013-04-09 16:51:13 +00:00			`; RUN: llvm-link %t.foo2.bc %t.foo1.bc -S \| FileCheck %s`

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61558 91177308-0d34-0410-b5e6-96231b3b80d8 2009-01-02 07:01:27 +00:00			`@G = addrspace(2) global i32 256`
