`make-byte-code' wraps `vector' doing some sanity check on the input
arguments. `vector' is in side-effect-and-error-free-fns so add
`make-byte-code' to side-effect-free-fns.

As function folding can generate 'setimm' insns handle them in the
`comp-propagate-insn'.
* lisp/emacs-lisp/comp.el (comp-propagate-insn): Handle 'setimm'
insn.
* lisp/emacs-lisp/comp.el (comp-symbol-values-optimizable): New
defconst.
(comp-function-call-maybe-remove): New logic to to remove
unnecessary `symbol-value' calls.
Do not perform trampoline optimization at speed 3 on function if their
name is not unique inside the compilation unit. Note that the
function can still be redefined in any other way therefore this is a
mitigation.

predicate.
(comp-call-optim-form-call): Perform trampoline optimization
for named functions only if they are unique within the current
compilation unit.
Is cleaner to have the function c-name as first argument of
'direct-call' 'direct-callref'. This is preparatory to anonymous
lambdas optimization.
* lisp/emacs-lisp/comp.el (comp-propagate-insn): Use c-name when
gathering the comp-func definition for direct calls.
(comp-call-optim-form-call): Add put c-name as first argument of
direct-call direct-callref when optimizing.

When closing emacs will inspect all directories from which it loaded
native compilation units. If it finds a ".eln.old" file it will try to
delete it, if it fails that means that another Emacs instance is using it.
When compiling a file we rename the file that was in the output path
in case it has been loaded into another Emacs instance.
When deleting a package we move any ".eln" or ".eln.old" files in the
package folder that we can't delete to `package-user-dir`. Emacs will
check that directory when closing and delete them.
* lisp/emacs-lisp/comp.el (comp--replace-output-file): Function called
from C code to finish the compilation process. It performs renaming of
the old file if necessary.
* lisp/emacs-lisp/package.el (package--delete-directory): Function to
delete a package directory. It moves native compilation units that it
can't delete to `package-user-dir'.
* src/alloc.c (cleanup_vector): Call dispose_comp_unit().
(garbage_collect): Call finish_delayed_disposal_of_comp_units().
* src/comp.c: Restore the signal mask using unwind-protect. Store
loaded native compilation units in a hash table for disposal on
close. Store filenames of native compilation units GC'd in a linked
list to finish their disposal when the GC is over.
(clean_comp_unit_directory): Delete all *.eln.old files in a
directory.
(clean_package_user_dir_of_old_comp_units): Delete all *.eln.old files
in `package-user-dir'.
(dispose_all_remaining_comp_units): Dispose of native compilation
units that are still loaded.
(dispose_comp_unit): Close handle and cleanup directory or arrange for
later cleanup if DELAY is true.
(finish_delayed_disposal_of_comp_units): Dispose of native compilation
units that were GC'd.
(register_native_comp_unit): Register native compilation unit for
disposal when Emacs closes.
* src/comp.h: Introduce cfile member in Lisp_Native_Comp_Unit.
Add declarations of functions that: clean directories of unused native
compilation units, handle disposal of native compilation units.
* src/emacs.c (kill-emacs): Dispose all remaining compilation units
right right before calling exit().

NUMBER_OF_PROCESSORS environment variable if system is Windows NT,
"nproc" if it is in PATH or a default of 1.
* lisp/emacs-lisp/comp.el (comp-run-async-workers): Pass the
compilation commands through a temporary file that is loaded by the
child process. This is also done all other operating systems, even
those that support long command lines. It should not be a problem
since libgccjit uses temporary files too.
* lisp/emacs-lisp/package.el (package-name-column-width)
(package-version-column-width, package-status-column-width)
(package-archive-column-width): New defcustoms.
