fd7a918e58 Resubmit an earlier patch of mine: 
reduce the size of relevant "ghostly" sentinels
by a pointer.

This attempt now makes the compactification dependent
on the configure variable LLVM_COMPACT_SENTINELS
and should not cause any bootstrap failures for
llvm-gcc any more.

Please note that this is not yet the final version,
and (as settled with Chris) I shall take out the
autofoo/cmake portions in the next days.

This will also lose the assertability on sentinel
dereferencing and operator++, but that seems
an acceptable price to pay for the simplified
build logic.

921be7a6f2 Remove SmallString::append_*int* methods; how many copies of int -> str 
conversion code do we really need?
 - S.append_uint(N) can be replaced with 'raw_svector_ostream(S) << N' which is
   somewhat slower due to the extra set up cost, but still plenty fast
   (especially if the svector set up cost can be amortized).

3c2d4bf97f Pass target triple string in to TargetMachine constructor. 
This is not just a matter of passing in the target triple from the module;
currently backends are making decisions based on the build and host
architecture. The goal is to migrate to making these decisions based off of the
triple (in conjunction with the feature string). Thus most clients pass in the
target triple, or the host triple if that is empty.

This has one important change in the way behavior of the JIT and llc.

For the JIT, it was previously selecting the Target based on the host
(naturally), but it was setting the target machine features based on the triple
from the module. Now it is setting the target machine features based on the
triple of the host.

For LLC, -march was previously only used to select the target, the target
machine features were initialized from the module's triple (which may have been
empty). Now the target triple is taken from the module, or the host's triple is
used if that is empty. Then the triple is adjusted to match -march.

The take away is that -march for llc is now used in conjunction with the host
triple to initialize the subtarget. If users want more deterministic behavior
from llc, they should use -mtriple, or set the triple in the input module.

763457e70b Twines: Support numeric conversion directly (uitostr, etc). 
- Provides static constructors for doing number to string conversions without
   using temporaries.

 - There are several ways to do this, I think given the Twine constraints this
   is the simplest one.

 - One FIXME for fast number -> hex conversion.

 - Added another comment on one last major bit of perf work Twines need, which
   is to make raw_svector_ostream more efficient.

b9cfbd94ab Shrink wrapping in PEI: 
- reduces _static_ callee saved register spills

- 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.

  ///    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.

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.

98f8ccfad0 Move the fast-path (<=i64) cases of various APInt methods inline 
and the slow-path cases out of line.  This speeds up instcombine
a bit in real world cases.  Patch contributed by m-s.

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.

- Creates uninitialized APInt. 
 - Prevents need for embedding arbitrary constants when used as an out
   parameter, for example.

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.
