[Backend] Bump to llvm/llvm-project@570885128351 (#7291)

This picks up a bug fix for AMDGPU v_permlane_swap:

llvm/llvm-project#144423
Without this fix, the v_permlane_swap is wrongly sunk.

Along the way we need to fix API changes:

Add header file for the class IRBuilder
Add missing default parameter in convertFuncOpToLLVMFuncOp
