0.3.0

• re-enabled Intel support
• HccRo/Wo/RwTexture* now output a SPIR-V format that matches it's element type.
  • see here for documentation https://github.com/heroseh/hcc/blob/main/docs/intrinsics.md#textures
• add addr_*_texture* functions that get the address of a texel from a texel used by atomics
• add bitcount function
• error when HCC_DISPATCH_GROUP is used in non-compute shader stages
• fix preprocessor crash when macro function brackets were not closed
• read only resources now return const so errors are reported when they are written to
• write only resources now report errors when they are read from
  • introduced a mutonly type qualifier to solve this
• fix preprocessor not erroring when too few parameters were provided
• fix the ternary operator by stopping it from processing the comma operator
• fix atomic_compare_exchange* SPIR-V codegen
• bool is now has a defined underlying type size of int32_t
  • this was previously undefined as we used to use SPIR-V OpTypeBool
  • bool is now not ABI compatible with CPU code, in future we should use u8 if u8 types are enabled
• remove boolean vectors, u/int32_t vectors should be used in it's place
• fix bug where typedef's used in function parameters could cause an SPIR-V error
  • the function data type parameters where not be deduplicated
• fix atomic functions memory sematics
• fix SPIR-V codegen for while and for loops with complex condition expressions
• fix for and while loop SPIR-V validation, extra block was being created and causing the loop merge block to be different
• fix for loop with no expression eg. for (;;)
• fix wave_active_prefix* SPIR-V validation errors
