octave: liboctave/numeric/oct-rand.cc annotate

annotate liboctave/numeric/oct-rand.cc @ 26369:0249ba4c9589

Fix static analyzer detected V668 issues (bug #55347). This patch adresses all V668 (check return value of "new" against NULL) except the following files: utils.cc:188 (keep the check in expression for clarity) * file-editor.cc, resource-manager.cc, shortcut-manager.cc, display.cc, file-editor-tab.cc, ft-text-renderer.cc, graphics.cc, oct-errno.in.cc, pager.cc, __init_fltk__.cc, audiodevinfo.cc, oct-parse.yy, oct-fftw.cc, oct-rand.cc, oct-spparms.cc, oct-env.cc, singleton-cleanup.cc: Remove checking for nullptr when pointer was created with new() which will throw an exception.
