a471c2ecda Next PPC long double bits. First cut at constants.
No compile-time support for constant operations yet,
just format transformations.  Make readers and
writers work.  Split constants into 2 doubles in
Legalize.

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.

3f6eb7419d Add APInt interfaces to APFloat (allows directly
access to bits).  Use them in place of float and
double interfaces where appropriate.
First bits of x86 long double constants handling 
(untested, probably does not work).

43421b3dd7 Next round of APFloat changes.
Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double.  Remove
the ConstantFP double interfaces.
Use APFloat functions for constant folding arithmetic
and comparisons.
(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)

ebbc95da49 Patch 10 for long double. Doing constants right needs expanding ConstantFP
to handle values bigger than double.  If we assume host==target and host
long double works correctly, this is not too bad, but we don't want to
have that limitation longterm.  I could implement accepting double
constants as long double or something like that, which would lead to
incorrect codegen with no errors; the more I think about that the worse
it seems.  Rather than do such a hack that would be backed out later,
I'm settling for giving reasonable error messages, for now.

because we didn't emit the same 3 abbrevs 2345 times :)

2453f71ae1 shave another 150K off of kc++, by using a 7-bit encoding for BB names
where we can.  This shrinks kc++'s down to 3368K, with a VST record of:

Isn't it nice to be able to optimizer bc size without touching the reader? :)

6da91d3c2c optimize constant layout. This fixes encoding of 181.mcf (by ensuring
integer structure idx's are emitted before constant expr geps) and shrinks
files slightly.  For example kc++ shrinks from 4326188 to 4240128 bytes.
