Chris Bieneman b8dbc6ffea [HLSL] Add ExternalSemaSource & vector alias ... HLSL vector types are ext_vector types, but they are also exposed via a template syntax `vector<T, #>`. This is morally equavalent to the code: ```c++ template <typename T, int Size> using vector = T __attribute__((ext_vector_type(Size))) ``` The problem is that templates aren't supported before HLSL 2021, and type aliases still aren't supported in HLSL. To resolve this (and other issues where HLSL can't represent its own types), we rely on an external AST & Sema source being registered for HLSL code. This patch adds the HLSLExternalSemaSource and registers the vector type alias. Depends on D127802 Differential Revision: https://reviews.llvm.org/D128012		2022-07-05 11:30:29 -05:00
