Allow bitwise or expressions and numeric literals in spirv_asm blocks (#3157)
* Add -spirv-core-grammar option to load alternate spirv defs
Also embed a version to use by default
* Use perfect hash for spv op lookup
* Neaten perfect hash embedding
* Refactor spirv grammar lookup in preperation for more kinds of lookups
* Load spirv capability list from spec
* Add all SPIR-V enums to lookup table
* regenerate vs projects
* appease msvc
* Use string slices for spir-v core grammar lookups
* wiggle
* comment
* Add OpInfo for spv ops
* regenerate vs projects
* Embed op names
* Add min/max operand counts and enum categories to spirv info
* neaten
* Operand kinds for spirv ops
* Store and embed all information relating to spirv enums and qualifiers
* Use SPIR-V spec to position instructions in spirv_asm blocks
* Neaten spir-v info embedding
* Neaten perfect hash embedding
* Add assignment syntax to spirv_asm snippets
* Better errors for spirv_asm parser
* Add warning for too many operands in spirv asm
* squash warnings
* neaten
* test wiggle
* Lookup enums for spirv
* Put OpCapability and OpExtension in the correct place for spirv_asm blocks
* Tests for OpCapability and OpExtension
* ci wiggle
* Add expected failure
* Allow raising immediate values to constant ids where necessary in spirv_asm blocks
* Allow bitwise or expressions and numeric literals in spirv_asm blocks
* test numeric literals
