40d080e3b7 Rename "fpaccuracy" metadata to the more generic "fpmath". That's because I'm
thinking of generalizing it to be able to specify other freedoms beyond accuracy
(such as that NaN's don't have to be respected).  I'd like the 3.1 release (the
first one with this metadata) to have the more generic name already rather than
having to auto-upgrade it in 3.2.

a106725fc5 Land the long talked about "type system rewrite" patch. This
patch brings numerous advantages to LLVM.  One way to look at it
is through diffstat:
 109 files changed, 3005 insertions(+), 5906 deletions(-)

Removing almost 3K lines of code is a good thing.  Other advantages
include:

1. Value::getType() is a simple load that can be CSE'd, not a mutating
   union-find operation.
2. Types a uniqued and never move once created, defining away PATypeHolder.
3. Structs can be "named" now, and their name is part of the identity that
   uniques them.  This means that the compiler doesn't merge them structurally
   which makes the IR much less confusing.
4. Now that there is no way to get a cycle in a type graph without a named
   struct type, "upreferences" go away.
5. Type refinement is completely gone, which should make LTO much MUCH faster
   in some common cases with C++ code.
6. Types are now generally immutable, so we can use "Type *" instead 
   "const Type *" everywhere.

Downsides of this patch are that it removes some functions from the C API,
so people using those will have to upgrade to (not yet added) new API.  
"LLVM 3.0" is the right time to do this.

There are still some cleanups pending after this, this patch is large enough
as-is.

9b75edbd14 Revert this. There's no way to verifiy indirect calls, and an optimizer can turn
indirect call into direct call, thus the verifier would reject something it
previously accepted.

This only rejects mismatches between target specific calling convention
and C/LLVM specific calling convention.
There are too many fastcc/C, coldcc/cc42 mismatches in the testsuite, these are
not reject by the verifier.

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.

c638fe5b8b For all RUN lines starting with "not", redirect stderr to /dev/null so tests
don't fail when (expected) error output is produced. This fixes 17 tests.

While I was there, I also made all RUN lines of the form "not llvm-as..." a bit
more consistent, they now all redirect stderr and stdout to /dev/null and use
input redirect to read their input.

e55a5806ac Do not allow attributes beyond a function's last
parameter, even if it is a varargs function.  Do
allow attributes on the varargs part of a call,
but not beyond the last argument.  Only allow
selected attributes to be on the varargs part of
a call (currently only 'byval' is allowed).  The
reasoning here is that most attributes, eg inreg,
simply make no sense here.

bc10247769 Get the verifier to check attributes on calls as well

are being passed to the varargs part of a varargs
function (llvm-as drops them on the floor anyway).

fa3a5915b1 Fix for PR1633: Verifier doesn't fully verify GC intrinsics
LLVM now enforces the following prototypes for the write barriers:

<ty>* @llvm.gcread(<ty2>*, <ty>**)
void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**)

And for @llvm.gcroot, the first stack slot is verified to be an alloca or a 
bitcast of an alloca.

Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these.
