f742e2fe70 Arm supports negative strides as well, add them. This lets us compile: 
CodeGen/ARM/arm-negative-stride.ll to:

LBB1_2: @bb
        str r1, [r3, -r0, lsl #2]
        add r0, r0, #1
        cmp r0, r2
        bne LBB1_2      @bb

6be85337b0 - 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).

a88c4a74f3 bugfix: When the source register of CALL_NOLINK was LR, the following code was emitted: 
mov lr, pc
    bx lr
So, the function was not called.
