  -----------
  [RISCV] Remove isel patterns for riscv.vfmerge with vector-vector operands. (#101277)

The vfmerge intrinsic is only used by clang for vfmerge.vfm. vmerge.vvm
for both int and float should use the llvm.vmerge intrinsic.

This patch removes the vector-vector support for llvm.vfmerge and
updates the tests to test what clang really uses.
