The goal of this PR is to facilitate integration of SPIRV Backend into misc 3rd party tools and libraries by means of exposing an API call that translate LLVM module to SPIR-V and write results into a string as binary SPIR-V output, providing diagnostics on fail and means of configuring translation in a style of command line options. An example of a use case may be Khronos Translator that provides bidirectional translation LLVM IR <=> SPIR-V, where LLVM IR => SPIR-V step may be substituted by the call to SPIR-V Backend API, implemented by this PR.
