Use #{`}#, #{,}# and #{,@}# as the quasiquote, unquote and
unquote-splicing operators, respectively. Previously they were named
escaping.
* module/language/elisp/compile-tree-il.scm (unquote?): Change "\," to
"#{,}#".
(unquote-splicing): Change "\,@" to "#{,@}#".
(#{compile-`}#): Rename from #{compile-\`}#.
* module/language/elisp/runtime/function-slot.scm: Import #{compile-`}#
instead of #{compile-\`}#, and re-export as #{`}# instead of as
#{\`}#.

If the function slot of a symbol contains a pair with `special-operator'
in the car and a procedure in the cdr, the procedure is called to
compile the form to Tree-IL. This is similar to other Emacs Lisp
implementations, in which special operators are subrs.
* module/language/elisp/compile-tree-il.scm: Restructured to store
special operator definitions in the function slot. Import `(language
elisp runtime)' for `defspecial'. Export special operators so that
`(language elisp runtime function-slot)' can re-export them.
(backquote?): Removed; the backquote symbol is defined as a special
operator, so it's no longer used in `compile-pair'.
(is-macro?, get-macro): Replaced by `find-operator'.
(find-operator): New procedure.

compile-quote): New special operators with definitions taken from the
pmatch form in `compile-pair'. There is no special operator `lambda';
it is now a macro, as in other Elisp implementations.
(compile-pair): Instead of directly compiling special forms, check for
a special operator object in the function slot.
* module/language/elisp/runtime.scm: Export `defspecial'.
(make-id): New function.
(built-in-macro): Prefix macros with `macro-'.

to read an expression.

Guile Emacs Lisp previously kept macros in a separate macro slot; now
macros are stored as macro objects in the function slot for
compatibility with other implementations.
* module/language/elisp/compile-tree-il.scm (macro-slot): Remove.
(is-macro?): Check that the argument is a symbol. Now-unnecessary
check removed in `compile-tree-il'.
(macro?, define-macro!, get-macro): Store macro definitions in the
function slot, not in a separate macro slot.
* module/language/elisp/runtime.scm (built-in-macro): Wrap the macro
function in a macro object (i.e., cons the symbol `macro' onto it).
* module/language/elisp/runtime/function-slot.scm: Move contents to

defining functions directly in this module.
* module/language/elisp/runtime/macro-slot.scm: Move contents to

GHIL is obsolete, and it's about time we got rid of it. Elisp and R5RS
were unmodified since their import from Guile-VM, so we ditch them too.
R5RS compilation is supported via compiling Scheme within an R5RS
environment.
Elisp will be supported when we merge in Daniel's work.
