more platforms than LLVM supports.

928b47ae2e Revamp long/ulong comparisons to use a much more efficient sequence (thanks 
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

d4c8bea47f Enable optimization suggested by Chris Lattner to not emit reloc stubs for 
static global variables whose addresses are taken.  This allows us to
convert the following code for taking the address of a static function foo

        addis r2, r30, ha16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")
        lwz r3, lo16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")(r2)

which also includes linker stub code emitted at the end of the .s file not
shown here, and replace it with this:

        addis r2, r30, ha16(l1__2E_foo_2-"L00001$pb")
        la r3, lo16(l1__2E_foo_2-"L00001$pb")(r2)

which in addition to not needing linker help, also has no load instruction.
For those not up on PowerPC mnemonics, la is shorthand for add immediate.

5efb75daed * Rename existing relocations to be more specific 
* Add relocations for refernces to non-lazy darwin stubs and implement
  them correctly.

With this change, we can correctly references external globals, and now
all but two UnitTests and all but 1 Regression/C tests pass.

More importantly, bugpoint-jit will start giving us useful testcases,
instead of always telling us that references to external globals don't
work :)

486ebfd704 Fix Shootout-C++/wc, which was broken by my recent changes to emit fewer 
reg-reg copies.  The necessary conditions for this bug are a GEP that is
used outside the basic block in which it is defined, whose components
other than the pointer are all constant zero, and where the use is
selected before the definition (backwards branch to successsor block).

longs, not to passing them into functions, which we already support.)

db869aad8c Eliminate another common source of moves that the register allocator 
shouldn't be forced to coalesce for us: folded GEP operations.  This too
fires thousands of times across the testsuite.

1f5308e5b5 When accessing the base register for global variables, use the register 
directly rather than making a copy for the register allocator to coalesce.
This kills thousands of live intervals across the testsuite.

c8b9f33ac0 * There is no reason for SpillWeights to be an instance var 
* Do not put fixed registers into the unhandled set.  This means they will
  never find their way into the inactive, active, or handled sets, so we
  can simplify a bunch of code.
