Clean up questionable code bits identified by clang sanitize.
* data.cc (Fnorm): in %!test, don't test with a single value which exceeds
range of single.
* find.cc (find_nonzero_elem_idx): Remove unused variable assignment to
n_to_find.
* load-save.cc (Fsave): Declare argc just before usage.
* ls-hdf5.cc (hdf5_read_next_data): Return from function immediately if type is
unrecognized.
* oct-stream.cc (octave_stream::read): Eliminate unnecessary initialization of
elts_to_read.
* octave-link.cc (F__octave_link_file_dialog__): Eliminate unnecessary
initialization of nel.
* pr-output.cc (set_real_format): Don't assign to function input variable
digits.
* str2double.cc (single_num): Initialize return value num at start of function.
* ov-complex.cc (octave_complex::double_value, octave_complex::float_value):
Eliminate unnecessary initialization of retval.
* ov-flt-complex.cc (octave_float_complex::double_value,
octave_float_complex::float_value):
Eliminate unnecessary initialization of retval.
* CSparse.cc (SparseComplexMatrix::inverse): Remove useless asignment to typ.
* CSparse.cc (SparseComplexMatrix::bsolve): Initialize anorm before using in
comparison.
* MatrixType.cc (matrix_complex_probe): Initialize typ to MatrixType::Unknown.
* dSparse.cc (SparseMatrix::inverse): Remove useless assignment to typ.
* dSparse.cc (SparseMatrix::bsolve): Initialize anorm before using in
comparison.
* lo-specfun.cc (gammainc): Remove useless assignment to err.
* data-conv.cc (oct_data_conv::string_to_data_type): Remove useless assignment
to input_is_output.
* str-vec.cc (string_vector::list_in_columns): Remove useless assignment to nc.
