  Changed paths:
    M clang/lib/CodeGen/CGBuiltin.cpp
    M clang/test/CodeGen/RISCV/rvb-intrinsics/riscv64-xtheadbb.c
    M clang/test/CodeGen/RISCV/rvb-intrinsics/riscv64-zbb.c

  Log Message:
  [RISCV] Add trunc instruction to the __builtin_riscv_ctz_64/__builtin_riscv_clz_64 IR.

These builtins were recently changed to return 'int' like the
similar __builtin_clz/__builtin_ctz builtins, but the IR generation
was not updated to use a truncate.
