014fe01ac8 Use statement expressions in Neon intrinsics defined as macros. 
This is in preparation for adding assignments to temporaries to ensure
that the proper type checking is done.

ec626b09cb Add a missing cast for Neon vsbl results. 
The bitwise operations are always done with unsigned values, but the result may
be signed.

a9ea9ef840 Add casts in arm_neon.h for result values in inline functions as well as macros. 
We should not rely on lax-vector-conversions for these intrinsics to work.

4be0bd79a4 Implement the first half of LiveDebugVariables. 
Scan the MachineFunction for DBG_VALUE instructions, and replace them with a
data structure similar to LiveIntervals. The live range of a DBG_VALUE is
determined by propagating it down the dominator tree until a new DBG_VALUE is
found. When a DBG_VALUE lives in a register, its live range is confined to the
live range of the register's value.

LiveDebugVariables runs before coalescing, so DBG_VALUEs are not artificially
extended when registers are joined.

The missing half will recreate DBG_VALUE instructions from the intervals when
register allocation is complete.

The pass is disabled by default. It can be enabled with the temporary command
line option -live-debug-variables.

c4fb38b821 I don't think it makes any sense to assert that the target supports SSE3 here. 
The user (i.e. whoever generated a call to the intrinsic in the first place) is
essentially asking for a particular instruction to be placed in the assembler.
If that instruction won't execute on the target machine, that's their problem
not ours.  Two buildbots with processors that don't support SSE3 were barfing
on the apm.ll test in CodeGen/X86 because of this assertion.
