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

* Fix memory issues.

* fix.
