Change uses of getTypeSize to getABITypeSize, getTypeStoreSize
...
or getTypeSizeInBits as appropriate in ScalarReplAggregates.
The right change to make was not always obvious, so it would
be good to have an sroa guru review this. While there I noticed
some bugs, and fixed them: (1) arrays of x86 long double have
holes due to alignment padding, but this wasn't being spotted
by HasStructPadding (renamed to HasPadding). The same goes
for arrays of oddly sized ints. Vectors also suffer from this,
in fact the problem for vectors is much worse because basic
vector assumptions seem to be broken by vectors of type with
alignment padding. I didn't try to fix any of these vector
problems. (2) The code for extracting smaller integers from
larger ones (in the "int union" case) was wrong on big-endian
machines for integers with size not a multiple of 8, like i1.
Probably this is impossible to hit via llvm-gcc, but I fixed
it anyway while there and added a testcase. I also got rid of
some trailing whitespace and changed a function name which
had an obvious typo in it.

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.

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.

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

# 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.

X86InstrInfo::isReallyTriviallyReMaterializable knows how to handle
with the isReMaterializable flag so that it is given a chance to handle
them. Without hoisting constant-pool loads from loops this isn't very
visible, though it does keep CodeGen/X86/constant-pool-remat-0.ll from
making a copy of the constant pool on the stack.

Re-apply 40504, but with a fix for the segfault it caused in oggenc:

Make the alignedload and alignedstore patterns always require 16-byte

a vector instruction is used for a scalar purpose, they can still require
the full vector alignment. And add a regression test for this.
