5f19cf5df8 The exception handling function info should be reset for each new 
function. The information isn't used heavily -- it's only used at the end
of exception handling emission -- so there's no need to cache it.

8b94a14a78 C bindings for libLLVMCore.a and libLLVMBitWriter.a. 
- The naming prefix is LLVM.
- All types are represented using opaque references.
- Functions are not named LLVM{Type}{Method}; the names became
  unreadable goop. Instead, they are named LLVM{ImperativeSentence}.
- Where an attribute only appears once in the class hierarchy (e.g.,
  linkage only applies to values; parameter types only apply to
  function types), the class is omitted from identifiers for
  brevity. Tastes like methods.
- Strings are C strings or string/length tuples on a case-by-case
  basis.
- APIs which give the caller ownership of an object are not mapped
  (removeFromParent, certain constructor overloads). This keeps
  keep memory management as simple as possible.

For each library with bindings:

  llvm-c/<LIB>.h       - Declares the bindings.
  lib/<LIB>/<LIB>.cpp  - Implements the bindings.

So just link with the library of your choice and use the C header
instead of the C++ one.

6e19896999 Objective-C was generating EH frame info like this: 
"_-[NSString(local) isNullOrNil]".eh = 0
        .no_dead_strip  "_-[NSString(local) isNullOrNil]".eh

The ".eh" should be inside the quotes.

8c33da5dc4 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.

that the elements are ordered in this way.

87b51bc2b0 1. Don't call Value::getName(), which is slow. 
2. Lower calls to fabs and friends to FABS nodes etc unless the function has
   internal linkage.  Before we wouldn't lower if it had a definition, which
   is incorrect.  This allows us to compile:

define double @fabs(double %f) {
        %tmp2 = tail call double @fabs( double %f )
        ret double %tmp2
}

into:

_fabs:
        fabs f1, f1

57810cdac4 Fix PR1628. When exception handling is turned on, 
labels are generated bracketing each call (not just
invokes).  This is used to generate entries in
the exception table required by the C++ personality.
However it gets in the way of tail-merging.  This
patch solves the problem by no longer placing labels
around ordinary calls.  Instead we generate entries
in the exception table that cover every instruction
in the function that wasn't covered by an invoke
range (the range given by the labels around the invoke).
As an optimization, such entries are only generated for
parts of the function that contain a call, since for
the moment those are the only instructions that can
throw an exception [1].  As a happy consequence, we
now get a smaller exception table, since the same
region can cover many calls.  While there, I also
implemented folding of invoke ranges - successive
ranges are merged when safe to do so.  Finally, if
a selector contains only a cleanup, there's a special
shorthand for it - place a 0 in the call-site entry.
I implemented this while there.  As a result, the
exception table output (excluding filters) is now
optimal - it cannot be made smaller [2].  The
problem with throw filters is that folding them
optimally is hard, and the benefit of folding them is
minimal.

[1] I tested that having trapping instructions (eg
divide by zero) in such a region doesn't cause trouble.
[2] It could be made smaller with the help of higher
layers, eg by having branch folding reorder basic blocks
ending in invokes with the same landing pad so they
follow each other.  I don't know if this is worth doing.
