Fix byte-compiler crash for legal dynamic-binding code

This should really be taken care of by a syntax normalisation step in
the frontend, but there is no such step for non-lexbind code yet.

* lisp/emacs-lisp/byte-opt.el (byte-optimize-letX): Tolerate bindingsa
without initialising expressions.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test cases.
