Subject: Use SPIR-V opcode names rather than numbers (#2571)

* s/emititng blobal/emitting global

* Use SPIR-V opcode names rather than numbers

* regenerate Visual Studio project files

* Use names for extended SPIR-V GLSL instructions

* Add missing operand for SPIR-V extended instruction

* Add warning aginst modifying generated hashing files

* Squash warnings on MSVC
