[BUG] The translator recursive type mapping algorithm works incorrectly

[MrSidims]

Please consider following LLVM IR sample:
%struct._ZTS4Args.Args = type { %struct._ZTS6Object.Object addrspace(4)* }
%struct._ZTS6Object.Object = type { i32 (%struct._ZTS6Object.Object addrspace(4), i32) }

Here we have 2 LLVM type declarations. The translator will recursively
go through structure members and then through element types of the
pointer types, creating the appropriate SPIR-V types and mapping them
on LLVM types. Due to a recursive nature of this algorithm, here we will
have '%struct._ZTS6Object.Object addrspace(4)*' be processed twice with
2 SPIR-V type declaration instruction being created.

work around - #1047
