Fix OpCopyObject from U32 to S32

Conversion from U32 to S32 can use neither OpCopyObject (different types),
nor OpSConvert (same bit width). Changed to OpBitcast.

Affects:

dEQP-VK.spirv_assembly.instruction.compute.indexing

Components: Vulkan

VK-GL-CTS issue: 874

Change-Id: I298c2687f3f6f08f28f928623a1002ec72a5a8f8
