  [Inliner] Copy attributes when deoptimize intrinsic is inlined

During inlining of call-site with deoptimize intrinsic callee we miss
attributes set on this call site. As a result attributes like deopt-lowering are
disappeared resulting in inefficient behavior of register allocator in codegen.

Just copy attributes for deoptimize call like we do for others calls.
