nir/spirv.h: Remove some cruft missed while merging

There were merge conflicts in spirv.h that got missed because they were in
a comment and so it still compiled.  This gets rid of them and we should be
on-par with upstream spirv->nir.

 ** Enumeration tokens for SPIR-V, in various styles:
 **   C, C++, C++11, JSON, Lua, Python
-<<<<<<< HEAD

->>>>>>> fdo-personal/nir-spirv
 ** - C will have tokens with a "Spv" prefix, e.g.: SpvSourceLanguageGLSL
 ** - C++ will have tokens in the "spv" name space, e.g.: spv::SourceLanguageGLSL
 ** - C++11 will use enum classes in the spv namespace, e.g.: spv::SourceLanguage::GLSL
 ** - Lua will use tables, e.g.: spv.SourceLanguage.GLSL
 ** - Python will use dictionaries, e.g.: spv['SourceLanguage']['GLSL']
