Add vendor module and tests for Qualcomm Hexagon HVX (Hexagon Vector eXtension) SIMD support. HVX provides wide vector operations in either 64-byte (512-bit) or 128-byte (1024-bit) mode. Note: u8x128/i8x128 types are not included because portable-simd currently limits lane count to 64 (bitmask operations use u64). In 128-byte HVX mode, u8x64 maps to a half-vector (512-bit).

Successor to #500 Note that llvm/llvm-project#182520 causes some problems in some use cases. Hopefully the fix lands soon to make it into 22.x and then into Rust. |
