hip: fix bf16 WMMA operand vector type for gfx11/gfx12 (#30885) The __builtin_amdgcn_wmma_f32_16x16x16_bf16_w32 (and _gfx12) builtins take their A/B operands as vectors of short (_ExtVector<16, short>
hip: fix bf16 WMMA operand vector type for gfx11/gfx12 (#30885) The __builtin_amdgcn_wmma_f32_16x16x16_bf16_w32 (and _gfx12) builtins take their A/B operands as vectors of short (_ExtVector<16, short> / _ExtVector<8, short>), not __bf16. Declaring the fragments as ext_vector_type(N) __bf16 fails to compile: error: cannot initialize a parameter of type 'short attribute((ext_vector_type(16)))' with an lvalue of type 'const bf16x16_t' (vector of 16 '__bf16' values) short and __bf16 are both 16-bit and the value is only ever passed to the builtin via reinterpret_cast over raw bytes, so changing the element type is bit-identical. The operand type has been short since the builtin was introduced, so this works across LLVM/ROCm versions without a version gate. Fixes HIP builds for RDNA3 (gfx1150/1151) and RDNA4 (gfx1200/1201).
