We were generating intrinsics for NEON fixed-point conversions that didn't
exist (e.g. float -> i16). There are two cases to consider:
+ iN is smaller than float. In this case we can do the conversion but need an
extend or truncate as well.
+ iN is larger than float. In this case using the NEON conversion would be
incorrect so we don't perform any combining.

The ARM backend currently has poor codegen for long sext/zext
operations, such as v8i8 -> v8i32. This patch addresses this
by performing a custom expansion in ARMISelLowering. It also
adds/changes the cost of such lowering in ARMTTI.
This partially addresses PR14867.

In r176898 I updated the cost model to reflect the fact that sext/zext/cast on
v8i32 <-> v8i8 and v16i32 <-> v16i8 are expensive.
This test case is so that we make sure to update the cost model once we fix
CodeGen.
