  [DebugInfo][InstCombine] When replacing bswap idiom, add DebugLoc to new insts (#114231)

Currently when InstCombineAndOrXor recognizes a bswap idiom and replaces
it with an intrinsic and other instructions, only the last instruction
gets the DebugLoc of the replaced instruction set to it. This patch
applies the DebugLoc to all the generated instructions, to maintain some
degree of attribution.
