* Ensure same enum values have consistent extension lists * val: fix checking of capabilities The operand for an OpCapability should only be checked for the extension or core version. The InstructionPass registers a capability, and all its implied sub-capabilities before actually checking the operand to an OpCapability. * Add basic support for SPIR-V 1.5 - Adds SPV_ENV_UNIVERSAL_1_5 - Command line tools default to spv1.5 environment - SPIR-V 1.5 incorporates several extensions. Now the disassembler prefers outputing the non-EXT or non-KHR names. This requires updates to many tests, to make strings match again. - Command line tests: Expect SPIR-V 1.5 by default * Test validation of SPIR-V 1.5 incorporated extensions Starting with 1.5, incorporated features no longer require the associated OpExtension instruction.
