Provide backtrace for byte-ops aref and aset

Browse source 
Produce synthetic backtrace entries for `aref` and `aset` byte-ops
when the index is non-fixnum, or is out of range for vector or record
arguments (bug#64613).

* src/bytecode.c (exec_byte_code): Detect type and range errors
in-line for aref and aset.
* src/data.c (syms_of_data): Declare symbols Qaref and Qaset.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests--byte-op-error-cases): Add test cases.
