b03eacdbf3 Fixed a bug that causes codegen of noop like add r0, r0, #0.

0111999a88 Starting implementation of the ELF32 ABI specification of varargs handling. 
LowerVASTART emits the right code if the subtarget is ELF32, the other intrinsics
(VAARG, VACOPY and VAEND) are not yet implemented.

ec58d9f9dd The PPC64 ELF ABI is "intended to use the same structure layout and calling convention rules 
as the 64-bit PowerOpen ABI" (Reference http://www.linux-foundation.org/spec/ELF/ppc64/).
Change all ELF tests to ELF32.

cfcd8da70b Addition to the previous commit for getCalleeSavedRegClasses: 
"The ELF ABI specifies F1-F8 registers as argument registers for double, not
F1-F10. This affects only ELF, not MachO."

b2c594f350 Arm supports negative strides as well, add them. This lets us compile: 
CodeGen/ARM/arm-negative-stride.ll to:

LBB1_2: @bb

        add r0, r0, #1
        cmp r0, r2

aa43e9f73b Fix a bug which caused us to never be able to use signed comparisons for 
equality comparisons of a constant.  This allows us to codegen the 'sintzero'
loop in PR1288 as:

LBB1_1: ;cond_next
        li r4, 0
        addi r2, r2, 1
        stw r4, 0(r3)
        addi r3, r3, 4
        cmpwi cr0, r2, -1
        bne cr0, LBB1_1 ;cond_next

instead of:

LBB1_1: ;cond_next
        addi r2, r2, 1
        li r4, 0
        xoris r5, r2, 65535
        stw r4, 0(r3)
        addi r3, r3, 4
        cmplwi cr0, r5, 65535
        bne cr0, LBB1_1 ;cond_next

This implements CodeGen/PowerPC/compare-simm.ll, and also cuts 74
instructions out of kc++.

9996663fc6 - Divides the comparisons in two types: comparisons that only use N and Z 
flags (ARMISD::CMPNZ) and comparisons that use all flags (ARMISD::CMP).
- Defines the instructions: TST, TEQ (ARM) and TST (Thumb).

eebc8a1bc5 Add support for the v1i64 type. This makes better code for this: 
#include <mmintrin.h>

extern __m64 C;

void baz(__v2si *A, __v2si *B)
{
  *A = C;
  _mm_empty();
}

We get this:

_baz:
        call "L1$pb"
"L1$pb":
        popl %eax
        movl L_C$non_lazy_ptr-"L1$pb"(%eax), %eax
        movq (%eax), %mm0
        movl 4(%esp), %eax
        movq %mm0, (%eax)
        emms
        ret

GCC gives us this:

_baz:
        pushl   %ebx
        call    L3
"L00000000001$pb":
L3:
        popl    %ebx
        subl    $8, %esp
        movl    L_C$non_lazy_ptr-"L00000000001$pb"(%ebx), %eax
        movl    (%eax), %edx
        movl    4(%eax), %ecx
        movl    16(%esp), %eax
        movl    %edx, (%eax)
        movl    %ecx, 4(%eax)
        emms
        addl    $8, %esp
        popl    %ebx
        ret
