Please take a look.
Description:
Increase sanity of integer division handling on ARM
- In the INT32 BinaryOpStub, fix type feedback collection for DIV,
bringing it in line with other platforms.
- In Lithium codegen, emit proper inlined code, don't call the stub.
- Drive-by fix: assert appropriate CpuFeaturesScope for SDIV.
