No offset appear now when the code isn't a call from bytecode.

* source-mapping/source-map.el (source-map-file): Add optional
output-file-name argument.

* source-mapping/source-map.el (source-map-file): Pass buffers as
arguments instead of binding them to standard-input and standard-output.

* source-mapping/source-map.el (source-map-file): `pp-buffer' after
printing.

* source-mapping/source-map-tests.el: New file. ERT tests for
source-map.el.
* source-mapping/boring-file: New file. Contains various reader syntax
to test `source-map-read' and `source-map-file'.

...and make lots of changes

* source-mapping/source-map.el: New file, replacing source-object.el.
(source-map-expression, source-map-list, source-map-symbol)
(source-map-vector, source-map-string, source-map-number)
(source-map-record, source-map-hash-table, source-map-char-table)
(source-map-byte-code, source-map-other): Renamed from `source-object'.
Added "code" slot that contains a string of the original form that was
read. Documented slots.
(source-map-top-level-form): New struct. Represents a top-level form and
contains a `source-object' for that expression.
(source-map-read): Skip whitespace and comments before reading. Bind a
few edebug variables to avoid corrupting offset data.
(source-map-file): New function. Outputs a separate file containing
`source-map-top-level-form's for the supplied Elisp file.

* source-mapping/source-object.el: New file. The entry point is the
function `source-object-read`. It uses edebug to read and store offsets
of sexps in the stream, then parses them into an AST-like structure, a
subtype of the cl-struct `source-object`. It contains the actual object
that was read, the start and end positions in the stream, and a
"members" field. For vectors and conses that field is a copy where the
contents are `source-object`s of the original sequence's contents.

README.md: correct run script name
scripts/perf-bench.sh: put in what I used last

(sourcemap-item-car) is like (car) for source maps

(sourcemap-read-sexpr) is the main routine
(test-source-read-sexpr) is a test of that

README.md: instructions for what's in this directory and how to use
test-debugger.elc: bytecode to run to see the new offset information
test-debugger.el: source code for the above

* scripts/compare-benches.el (insert-org-file-link): Call
`file-relative-name` on its argument.

* scripts/compare-benches.el: New script. Runs elisp-benchmarks on
multiple executables concurrently and collects a variety of data from
it. Execute it with the -h flag for usage information.

* scripts/flamegraph.pl:
* scripts/difffolded.pl: Added so compare-benches.el can use them.

* elisp-benchmarks-1.6/elisp-benchmarks.el (elisp-benchmarks-run):
Modified to work with compare-benches.el.

* elisp-benchmarks-1.6/elisp-benchmarks-orig.el: New file. Backup of
original elisp-benchmarks.el.

* README.md: Mention the above two changes.
