to Brian and the Sun compiler for pointing out that the obvious works :)

This also enables folding all long comparisons into setcc and branch
instructions: before we could only do == and !=

For example, for:
void test(unsigned long long A, unsigned long long B) {
   if (A < B) foo();
 }

We now generate:

test:
        subl $4, %esp
        movl %esi, (%esp)
        movl 8(%esp), %eax
        movl 12(%esp), %ecx
        movl 16(%esp), %edx
        movl 20(%esp), %esi
        subl %edx, %eax
        sbbl %esi, %ecx
        jae .LBBtest_2  # UnifiedReturnBlock
.LBBtest_1:     # then
        call foo
        movl (%esp), %esi
        addl $4, %esp
        ret
.LBBtest_2:     # UnifiedReturnBlock
        movl (%esp), %esi
        addl $4, %esp
        ret

Instead of:

test:
        subl $12, %esp
        movl %esi, 8(%esp)
        movl %ebx, 4(%esp)
        movl 16(%esp), %eax
        movl 20(%esp), %ecx
        movl 24(%esp), %edx
        movl 28(%esp), %esi
        cmpl %edx, %eax
        setb %al
        cmpl %esi, %ecx
        setb %bl
        cmove %ax, %bx
        testb %bl, %bl
        je .LBBtest_2   # UnifiedReturnBlock
.LBBtest_1:     # then
        call foo
        movl 4(%esp), %ebx
        movl 8(%esp), %esi
        addl $12, %esp
        ret
.LBBtest_2:     # UnifiedReturnBlock
        movl 4(%esp), %ebx
        movl 8(%esp), %esi
        addl $12, %esp
        ret

* Get rid of appending -lbz2 and -lz to ExtraLibs now that we don't need
  them any more.
* Fix the dist-check target so that EXTRA_DIST can be defined AFTER the
  include of Makefile.common. This is needed because Makefile.common
  provides variable definitions that may need to be used in computing the
  value of EXTRA_DIST.
* Clean up some "distdir" target output.

* organize programs we test for properly
* add new programs needed for documentation generation
* Adjust install paths so llvm stuff doesn't muck up /usr/local or /usr if
  $prefix is set to those.

llvm-svn: 18327

* Provide support for ENABLE_DOXYGEN
* New tools that documentation generation requires

llvm-svn: 18326

llvm-svn: 18325

* Implement optional doxygen doc generation
* Implement HTML and doxygen installation

llvm-svn: 18324

Reworked branching so we don't handle BAs specially. It just updates the branchTO regardless of what type of branch it is.

llvm-svn: 18322

* Ensure things installed to same place are all getting there by using a
  variable to name that place.
* Make sure missing index.html, images and *.css files get installed.

llvm-svn: 18321

* fix the links to not be in an html subdir as that's not how this gets
  installed (anymore).

llvm-svn: 18320

llvm-svn: 18319

* Implement installation of doxygen and html documentation
* Fix it so it works with objdir != srcdir.

llvm-svn: 18318

* Add an ENVIRONMENT section to describe LLVM_LIB_SEARCH_PATH

This file was originally doxygen.cfg, but it needs to be configured to get
the right srcdir/objdir paths for things. This is needed because building
the doxygen will now be part of the install and dist-check targets.

llvm-svn: 18315

Fixed bug where instructions in the kernel were not ordered right to preserve dependencies in a cycle.

llvm-svn: 18314

casts through, but they will only be sbyte -> ubyte in this test case so
make sure we don't let any other kinds through.

llvm-svn: 18313

* Make sure we handle signed to unsigned conversion correctly
* Move this visitSetCondInst case to its own method.
