4f95d2bda4 revert r78048, it isn't worth using assertingvh here.

48b2f3e485 Factor some of the constants+context related code out into a separate header, to make LLVMContextImpl.h 
not hideous.  Also, fix some MSVC compile errors.

0a0193edf9 switch ValueMap to using AssertingVH. This is an old patch I had laying 
around in a tree I forgot about.

d1319ef308 Remove Value::setName(const char*). 
- Split into a separate patch because there is a slight functionality change,
   it is no longer valid to call setName(0), which was equivalent to
   setName(""). I'm hoping no one depends on this...

21cc4460ef Add support for embedded metadata to LLVM. This introduces two new types of 
Constant, MDString and MDNode which can only be used by globals with a name
that starts with "llvm." or as arguments to a function with the same naming
restriction.

722272df41 Add two new classes: WeakVH and AssertingVH. These are both "ValueHandles", 
which are effectively smart pointers to Value*'s.  They are both very light
weight and simple, and react to values being destroyed or being RAUW'd.

WeakVN does a best effort to follow a value around, including through RAUW 
operations and will get nulled out of the value is destroyed.  This is useful
for the eventual "metadata that references a value" work, because it is a
reference to a value that does not show up on its use_* list.

AssertingVH is a pointer that compiles down to a dumb raw pointer when 
assertions are disabled.  When enabled, it emits an assertion if the 
pointed-to value is destroyed while it is still being referenced.  This
is very useful for Maps and other things, and should have caught the recent
bugs in CallGraph and Reassociate, for example.

5d0392c6b3 Factorize code: remove variants of "strip off 
pointer bitcasts and GEP's", and centralize the
logic in Value::getUnderlyingObject.  The
difference with stripPointerCasts is that
stripPointerCasts only strips GEPs if all
indices are zero, while getUnderlyingObject
strips GEPs no matter what the indices are.

944fac71e0 Switch the asmprinter (.ll) and all the stuff it requires over to 
use raw_ostream instead of std::ostream.  Among other goodness,
this speeds up llvm-dis of kc++ with a release build from 0.85s
to 0.49s (88% faster).

Other interesting changes:
 1) This makes Value::print be non-virtual.
 2) AP[S]Int and ConstantRange can no longer print to ostream directly, 
    use raw_ostream instead.
 3) This fixes a bug in raw_os_ostream where it didn't flush itself 
    when destroyed.
 4) This adds a new SDNode::print method, instead of only allowing "dump".


A lot of APIs have both std::ostream and raw_ostream versions, it would
be useful to go through and systematically anihilate the std::ostream 
versions.

This passes dejagnu, but there may be minor fallout, plz let me know if
so and I'll fix it.
