b9cfbd94ab Shrink wrapping in PEI:
- reduces _static_ callee saved register spills
  and restores similar to Chow's original algorithm.
- iterative implementation with simple heuristic
  limits to mitigate compile time impact.
- handles placing spills/restores for multi-entry,
  multi-exit regions in the Machine CFG without
  splitting edges.
- passes test-suite in LLCBETA mode.

Added contains() method to ADT/SparseBitVector.

d0dfbe096d fix overflow checks in SmallVector:
"The code was doing "if (End+NumInputs > Capacity) ...". If End is
close to 0xFFFFFFFF and NumInputs is large, it'll overflow, the
condition will come out false, and the vector won't grow to
accommodate the new elements, and the program will crash in memmove."

2491e4657d Add a simple type-safe bit-mangling pointer union class. This allows
you to do things like:

  ///    PointerUnion<int*, float*> P;
  ///    P = (int*)0;
  ///    printf("%d %d", P.is<int*>(), P.is<float*>()); // prints "1 0"
  ///    X = P.get<int*>();     // ok.
  ///    Y = P.get<float*>();   // runtime assertion failure.
  ///    Z = P.get<double*>();  // does not compile.
  ///    P = (float*)0;
  ///    Y = P.get<float*>();   // ok.
  ///    X = P.get<int*>();     // runtime assertion failure.

e30173ac33 Replace the PointerLikeTypeTraits::getNumLowBitsAvailable
function with a new NumLowBitsAvailable enum, which makes the
value available as an integer constant expression.

Add PointerLikeTypeTraits specializations for Instruction* and
Use** since they are only guaranteed 4-byte aligned.

Enhance PointerIntPair to know about (and enforce) the alignment
specified by PointerLikeTypeTraits.  This should allow things 
like PointerIntPair<PointerIntPair<void*, 1,bool>, 1, bool> 
because the inner one knows that 2 low bits are free.

helper.  This allows us to convert numbers to hex without necessarily
needing to make a std::string to hold the result.

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.

fad86b003a Rework the routines that convert AP[S]Int into a string. Now, instead of
returning an std::string by value, it fills in a SmallString/SmallVector
passed in.  This significantly reduces string thrashing in some cases.

More specifically, this:
 - Adds an operator<< and a print method for APInt that allows you to 
   directly send them to an ostream.
 - Reimplements APInt::toString to be much simpler and more efficient
   algorithmically in addition to not thrashing strings quite as much.

This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the
asmprinter.  This also fixes a bug I introduced into the asmwriter in a
previous patch w.r.t. alias printing.

fed90b6d09 Fold the useful features of alist and alist_node into ilist, and
a new ilist_node class, and remove them. Unlike alist_node,
ilist_node doesn't attempt to manage storage itself, so it avoids
the associated problems, including being opaque in gdb.

Adjust the Recycler class so that it doesn't depend on alist_node.
Also, change it to use explicit Size and Align parameters, allowing
it to work when the largest-sized node doesn't have the greatest
alignment requirement.

Change MachineInstr's MachineMemOperand list from a pool-backed
alist to a std::list for now.

needed.

0123b7dcfa Make tblgen a little smarter about constants smaller than i32. Currently,
tblgen will complain if a sign-extended constant does not fit into a
data type smaller than i32, e.g., i16. This causes a problem when certain
hex constants are used, such as 0xff for byte masks or immediate xor
values.

tblgen will try the sign-extended value first and, if the sign extended
value would overflow, it tries to see if the unsigned value will fit.
Consequently, a software developer can now safely incant:

	(XORHIr16 R16C:$rA, 0xffff)

which is somewhat clearer and more informative than incanting:

	(XORHIr16 R16C:$rA, (i16 -1))

even if the two are bitwise equivalent.

Tblgen also outputs the 64-bit unsigned constant in the generated ISel code
when getTargetConstant() is invoked.

95da16e288 Changed profiling method for ImmutableMap to once again just use its
unique ImutAVLTree* for profiling.

Modified ImutAVLTree:
 (1) changed ComputeHash() to ComputeDigest() and
 (2) changed Profile() to use the computed digest and
 (3) modified insertion of IMutAVLTree into the FoldingSet owned by
     the ImutAVLTreeFactory object to use profiling instead of computing
     a direct hash.  This fixes a bug where our abuse of the FoldingSet would
     not work when the FoldingSet was resized.

f357afb404 Modified node creation of ImutAVLTree to do a hash lookup for an existing
node in the FoldingSet of nodes held by the Factory object.  If we
we find a node with a matching hash, we do a full structural comparison.
Nodes are also now inserted into the FoldingSet only when we mark them
Immutable, as their children can change during intermediate-rebalancing.

The 'Profile' method for ImutAVLTree is no longer used when looking up
existing ImutAVLTrees with a given set of contents; instead the Profile method
is used by other clients that wish to insert such a tree into a folding set.
This means that we are not using FoldingSet in ImutAVLTreeFactory in the way
it was intended, but instead are using it as an opaque hashtable.

cadf873c83 Added additional overloaded operators for APSInt to match the operators of
APInt.

While some operators were already specifically overloaded for APSInt, others
resulted in using the overloaded operator methods in APInt, which would result
in the signedness bit being lost.

Modified the APSInt(APInt&) constructor to be "explicit" and to take an
extra (optional) flag to indicate the signedness.  Making the ctor explicit
will catch any implicit conversations between APSInt -> APInt -> APSInt that
results in the signedness flag being lost.

6518f5fcbf Replaced (FoldingSet) profiling of ImutAVLTree with a hashing based scheme. The
problem was that we previously hashed based on the pointers of the left and
right children, but this is bogus: we can easily have different trees that
represent the same set. Now we use a hashing based scheme that compares the
*contents* of the trees, but not without having to do a full scan of a tree. The
only caveat is that with hashing is that we may have collisions, which result in
two different trees being falsely labeled as equivalent. If this becomes a
problem, we can add extra data to the profile to hopefully resolve most
collisions.

a753f703d1 Made 'profiling' of objects in a FoldingSet trait-based using FoldingSetTrait
instead of always assuming that the stored objects had a method called
'Profile'. The default behavior is to dispatch to a 'Profile' method (as
before), but via template specialization this behavior can now be overridden by
clients.

Added templated class 'FoldingSetNodeWrapper', a generic wrapper class that
allows one to insert objects into a FoldingSet that do not directly inherit from
FoldingSetNode. This is useful for inserting objects that do not always need to
pay the overhead of inheriting from FoldingSetNode, or were designed with that
behavior in mind.

an iterator, since the implementation returned an iterator that pointed to a

returning an iterator if the user just wants to find the value of a key).

e509e7a178 Implemented "FIXME" in ImutAVLTree: isEqual() now also compares the *data* value
and not just the key value when comparing trees. To do this we added data_type
and data_type_ref to the ImutContainerInfo trait classes. For values stored in
the tree that do not have separate key and data components, data_type is simply
a typedef of bool, and isDataEqual() always evaluates to true. This allows us to
support both ImmutableSet and ImmutableMap using the same underlying logic.

d2128a7ca5 cleanup this code, making it more "llvm-like".
Add comments to reset indicating that it deletes its pointer.
Add a new take() method, which can be used to get the pointer
without it being deleted.

ffe9e63c4a Use references in DF iterators. This eliminates copy-ctor calls on huge objects (graphs)

41ff20bff4 Use vector for child storage instead of map. This will also make
our life during future GraphTraits'ing slightly easier.
