Instruction-level control with Inline Elementwise ASM in Triton

Triton provides an inline_asm_elementwise function that allows injecting elementwise PTX instructions into Triton kernels.

• The post demonstrates using the rcp.approx instruction to compute fast approximate reciprocals.
• The compilation pipeline lowers Triton kernels through MLIR and LLVM IR to PTX and then to CUBIN.
