Anton Korobeynikov 506eaf7915 Next stage into switch lowering refactoring 
1. Fix some bugs in the jump table lowering threshold
2. Implement much better metric for optimal pivot selection
3. Tune thresholds for different lowering methods
4. Implement shift-and trick for lowering small (<machine word
length) cases with few destinations. Good testcase will follow.

Reid Spencer 91b273ae39 XFAIL this test for now. It will be a while before I can implement this 
intrinsic properly in SDISel.

Anton Korobeynikov 915e61736b Properly emit range comparisons for switch cases, where neighbour cases 
go to the same destination. Now we're producing really good code for
switch-lower-feature.ll testcase

Lauro Ramos Venancio 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).

Reid Spencer c3d87685ad For PR1297: 
Update these test cases to use proper signatures for bswap which is now
and overloaded intrinsic. Its name must be of the form llvm.bswap.i32.i32
since both the parameter and the result or of type "iAny". Also, the
bit counting intrinsics changed to always return i32.

Lauro Ramos Venancio a88c4a74f3 bugfix: When the source register of CALL_NOLINK was LR, the following code was emitted: 
mov lr, pc
    bx lr
