f6e98c8cf5 Change some old-style casts to C++ style casts to avoid warnings in XPS 
compilation. This change has been waiting in the wings for a long time but
since Misha just did a global change, I figured now was the time to commit
it.

a416f4bbf3 * store immediate values as int64_t, not int. come on, we should be happy 
when there are immediates, let's not worry about the memory overhead of
this :)

* add addU64Imm(uint64_t val) to machineinstrbuilder

(seriously: this seems required to support 64-bit immediates cleanly. if it
_really_ gets on your nerves, feel free to pull it out ;) )

3a10f491f0 add support for prefix/suffix strings to go around GlobalValue(s) 
(which may or be function pointers) in the asmprinter. For the moment,
this changes nothing, except the IA64 backend which can use this to write:

  data8.ua  @fptr(blah__blah__mangled_function_name)

  (by setting FunctionAddrPrefix/Suffix to "@fptr(" / ")")

b3103a3768 Rewrite this class, making the following improvements: 
1. It now actually uses tarjan's algorithm, so it is a efficient inverse
     ackerman's function for union operations, not linear time.
  2. It now stores one copy of the data in the set instead of two.
  3. It now works for elements other than pointers.
  4. It now has a more STL-like interface that exposes iterators instead
     of internal implementation details.

fdbedbbb45 Switch from using an ilist for uses to using a custom doubly linked list. 
This list does not provide the ability to go backwards in the list (its
more of an unordered collection, stored in the shape of a list).

This change means that use iterators are now only forward iterators, not
bidirectional.

This improves the memory usage of use lists from '5 + 4*#use' per value to
'1 + 4*#use'.  While it would be better to reduce the multiplied factor,
I'm not smart enough to do so.  This list also has slightly more efficient
operators for manipulating list nodes (a few less loads/stores), due to not
needing to be able to iterate backwards through the list.

This change reduces the memory footprint required to hold 176.gcc from
66.025M -> 57.687M, a 14% reduction.  It also speeds up the compiler,
7.73% in the case of bytecode loading alone (release build loading 176.gcc).

ee6bc42f3e * Make some methods more const correct. 
* Change the FunctionCalls and AuxFunctionCalls vectors into std::lists.
  This makes many operations on these lists much more natural, and avoids
  *exteremely* expensive copying of DSCallSites (e.g. moving nodes around
  between lists, erasing a node from not the end of the vector, etc).

With a profile build of analyze, this speeds up BU DS from 25.14s to
12.59s on 176.gcc.  I expect that it would help TD even more, but I don't
have data for it.

This effectively eliminates removeIdenticalCalls and children from the
profile, going from 6.53 to 0.27s.

Based on the ilist changes avoid allocating an entire Use object for the
end of the Use chain.  This saves 8 bytes of memory for each Value allocated

memory savings.

3f035ee52d There is no reason to include ostream here, include iosfwd instead. 
This file was schizophrenic when it came to representing sizes.  In some
cases it represented them as 'unsigneds', which are not enough for 64-bit
hosts.  In other cases, it represented them as uint64_t's, which are
inefficient for 32-bit hosts.

This patch unifies all of the sizes to use size_t instead.

c6c1106909 Instead of storing operands as std::vector<Use>, just maintain a pointer 
and num operands in the User class.  this allows us to embed the operands
directly in the subclasses if possible.  For example, for binary operators
we store the two operands in the derived class.

The has several effects:
  1. it improves locality because the operands and instruction are together
  2. it makes accesses to operands faster (one less load) if you access them
     through the derived class pointer.  For example this:

Value *GetBinaryOperatorOp(BinaryOperator *I, int i) {
  return I->getOperand(i);
}

Was compiled to:

_Z19GetBinaryOperatorOpPN4llvm14BinaryOperatorEi:
        movl    4(%esp), %edx
        movl    8(%esp), %eax
        sall    $4, %eax
        movl    24(%edx), %ecx
        addl    %ecx, %eax
        movl    (%eax), %eax
        ret

and is now compiled to:

_Z19GetBinaryOperatorOpPN4llvm14BinaryOperatorEi:
        movl    8(%esp), %eax
        movl    4(%esp), %edx
        sall    $4, %eax
        addl    %edx, %eax
        movl    44(%eax), %eax
        ret

Accesses through "Instruction*" are unmodified.

   3. This reduces memory consumption (by about 3%) by eliminating 1 word of
      vector overhead and a malloc header on a seperate object.
   4. This speeds up gccas about 10% (both debug and release builds) on
      large things (such as 176.gcc).  For example, it takes a debug build
      from 172.9 -> 155.6s and a release gccas from 67.7 -> 61.8s

766ad3378c This giant patch speeds up Type::isSized(). Before, this would have to search 
large nested types over and over again to determine if they are sized or not.
Now, isSized() is able to make snap decisions about all concrete types, which
are a common occurance (and includes all primitives).

On 177.mesa, this speeds up DSE from 39.5s -> 21.3s and GCSE from
13.2s -> 11.3s, reducing gccas time from 80s -> 61s (this is a debug build).

DSE and GCSE are still too slow on this testcase, but this is a simple
improvement.
