- Redefines `DXILAttribute` to denote a function attribute, compatible to how it was define in DXC/LLVM 3.7 - Fix how `DXILAttribute` is emitted to be a struct of set attributes instead of an "or" of the enums - Implement the lowering of `DXILAttribute` to LLVM function attributes in `DXILOpBuilder.cpp`. A custom mapping is defined. - Audit all current ops to specify the correct attributes consistent with DXC. This is done here to allow for testing. - Update testcases in `llvm/test/CodeGen/DirectX` of all ops with attributes to match that attributes are set - Update testcases of ops that had previously incorrectly set attributes to check there is no attributes set - Defines `DXILProperty` to denote the other type of attributes from DXC used to query properties. - Emit `DXILProperty` as a struct of set attributes. - Updates `DXIL.td` to specify applicable `DXILProperty`s on ops Note: `DXILProperty` was referred to as 'queryable attributes' in design discussion. Changed to property to allow for better expression in `DXIL.td` Resolves #114461 Resolves #115912
