Generate spvasm.vim
Generate a vim syntax file for SPIR-V assembly. Copy the resulting spvasm.vim into your $HOME/.vim/syntax directory to get syntax highlighting in Vim. Also, suggest that the grammar file include information about what opcodes can be used in OpSpecConstantOp.

* [Utility filters](#utility-filters)

* Build target `spirv-tools-vimsyntax` generates file `spvasm.vim`.

Copy that file into your `$HOME/.vim/syntax` directory to get SPIR-V assembly syntax

highlighting in Vim. This build target is not built by default.
