  -----------
  [AMDGPU] Implement llvm.lround intrinsic lowering. (#98970)

This patch enables the target-independent lowering of llvm.lround via
GlobalISel. For SelectionDAG, the instrinsic is custom lowered for
AMDGPU. In order to support vector floating point input for llvm.lround,
this patch extends the target independent APIs and provide support for
scalarizing. pr98950 is needed to let verifier allow vector floating
point types
