c92da3882e There are times when the coalescer would not coalesce away a copy but the copy 
can be eliminated by the allocator is the destination and source targets the
same register. The most common case is when the source and destination registers
are in different class. For example, on x86 mov32to32_ targets GR32_ which
contains a subset of the registers in GR32.

The allocator can do 2 things:
1. Set the preferred allocation for the destination of a copy to that of its source.
2. After allocation is done, change the allocation of a copy destination (if
   legal) so the copy can be eliminated.

This eliminates 443 extra moves from 403.gcc.

3c3ddb3a85 Enable more fold (sext (load x)) -> (sext (truncate (sextload x))) 
transformation. Previously, it's restricted by ensuring the number of load uses
is one. Now the restriction is loosened up by allowing setcc uses to be
"extended" (e.g. setcc x, c, eq -> setcc sext(x), sext(c), eq).

cdf43b1fad If a loop termination compare instruction is the only use of its stride, 
and the compaison is against a constant value, try eliminate the stride
by moving the compare instruction to another stride and change its
constant operand accordingly. e.g.

loop:
...
v1 = v1 + 3
v2 = v2 + 1
if (v2 < 10) goto loop
=>
loop:
...
v1 = v1 + 3
if (v1 < 30) goto loop

02e4fa7d5f Strength reduction improvements. 
- Avoid attempting stride-reuse in the case that there are users that
   aren't addresses. In that case, there will be places where the
   multiplications won't be folded away, so it's better to try to
   strength-reduce them.

 - Several SSE intrinsics have operands that strength-reduction can
   treat as addresses. The previous item makes this more visible, as
   any non-address use of an IV can inhibit stride-reuse.

 - Make ValidStride aware of whether there's likely to be a base
   register in the address computation. This prevents it from thinking
   that things like stride 9 are valid on x86 when the base register is
   already occupied.

Also, XFAIL the 2007-08-10-LEA16Use32.ll test; the new logic to avoid
stride-reuse elimintes the LEA in the loop, so the test is no longer
testing what it was intended to test.

5c0d6ed325 Add support for byval function whose argument is not 32 bit aligned. 
To do this it is necessary to add a "always inline" argument to the
memcpy node. For completeness I have also added this node to memmove
and memset.  I have also added getMem* functions, because the extra
argument makes it cumbersome to use getNode and because I get confused
by it :-)

better since the run time value can be arbitrarily large.

46abf91f73 Added C and Ocaml bindings for functions, basic blocks, and 
instruction creation. No support yet for instruction introspection.

Also eliminated allocas from the Ocaml bindings for portability,
and avoided unnecessary casts.

a37c9f7506 When both x/y and x%y are needed (x and y both scalar integer), compute 
both results with a single div or idiv instruction. This uses new X86ISD
nodes for DIV and IDIV which are introduced during the legalize phase
so that the SelectionDAG's CSE can automatically eliminate redundant
computations.

8ef426baa3 Adding ocaml language bindings for the vmcore and bitwriter libraries. These are 
built atop the C language bindings, and user programs can link with them as 
such:

  # Bytecode
  ocamlc -cc g++ llvm.cma llvmbitwriter.cma -o example example.ml
  # Native
  ocamlopt -cc g++ llvm.cmxa llvmbitwriter.cmxa -o example.opt example.ml

The vmcore.ml test exercises most/all of the APIs thus far bound. Unfortunately,
they're not yet numerous enough to write hello world. But:

  $ cat example.ml
  (* example.ml *)
  
  open Llvm
  open Llvm_bitwriter
  
  let _ =
    let filename = Sys.argv.(1) in
    let m = create_module filename in
    
    let v = make_int_constant i32_type 42 false in
    let g = define_global "hello_world" v m in
    
    if not (write_bitcode_file m filename) then exit 1;
    
    dispose_module m;

  $ ocamlc -cc g++ llvm.cma llvm_bitwriter.cma -o example example.ml
  File "example.ml", line 11, characters 6-7:
  Warning Y: unused variable g.
  $ ./example example.bc
  $ llvm-dis < example.bc
  ; ModuleID = '<stdin>'
  @hello_world = global i32 42            ; <i32*> [#uses=0]

The ocaml test cases provide effective tests for the C interfaces.

8c33da5dc4 Fix for PR1633: Verifier doesn't fully verify GC intrinsics 
LLVM now enforces the following prototypes for the write barriers:

<ty>* @llvm.gcread(<ty2>*, <ty>**)
void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**)

And for @llvm.gcroot, the first stack slot is verified to be an alloca or a 
bitcast of an alloca.

Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these.
