This fix is prompted by Emacs bug#71744.
The working hypothesis is that there are some bugs in Emacs,
and some in GCC’s diagnostics, and that this patch
fixes the Emacs bugs and works around the GCC diagnostic bugs.
The hypothesis is that GCC diagnostic bugs occur when GCC
coalesces variables or temporaries and some variables
are clobbered by setjmp and some vars/temps are not.
Part of this hypothesis involves GCC diagnosing the wrong variables.
Instead of ignoring the diagnostics, which the hypothesis suggests
indicate either problems in Emacs or in GCC, fix the Emacs bugs
and pacify the GCC false positives, with comments about the GCC bugs.
GCC’s true positives are helpful enough in squashing obscure bugs like
Emacs bug#71744, that it’s worth going to some effort to pacify
-Wclobbered instead of ignoring it.
* src/bytecode.c: Do not ignore -Wclobbered.
(exec_byte_code): Fix violations of the C standard, where setjmp
clobbered quitcounter and bc.  If GCC_LINT && __GNUC__ && !__clang__,
work around GCC -Wclobbered warnings for bytestr_data and vectorp.

This makes comparison functions (=, /=, <, <=, >, >=, min, max) quite
a bit faster (10-20 %).  Bytecode ops on fixnums are not affected,
nor is `value<`.

* src/data.c (arithcompare): Simplify the code to reduce the number of
branches.  Remove the comparison code argument; instead, return the
relation encoded as bits, which can be tested cheaply.  All callers
adapted.
* src/lisp.h (enum Arith_Comparison): Remove.
(Cmp_Bit_*, cmp_bits_t): New.

Keep the name consistent with the naming used in the ELisp world.

* src/pdumper.c (dump_object_emacs_ptr, dump_do_fixup):
* src/eval.c (eval_sub, funcall_general, funcall_lambda):
* src/alloc.c (CHECK_ALLOCATED_AND_LIVE_SYMBOL, survives_gc_p):
* src/data.c (Fcl_type_of, Ffset, Fnative_comp_function_p)
(Fsubr_native_lambda_list, Finteractive_form):
* src/comp.c (check_comp_unit_relocs):
* src/bytecode.c (exec_byte_code):

* src/lisp.h (NATIVE_COMP_FUNCTIONP, NATIVE_COMP_FUNCTION_DYNP):
Rename from `SUBR_NATIVE_COMPILEDP` and `SUBR_NATIVE_COMPILED_DYNP`.

In preparation for the use of `PVEC_COMPILED` objects for
interpreted functions, rename them to use a more neutral name.

* src/lisp.h (enum pvec_type): Rename `PVEC_COMPILED` to `PVEC_CLOSURE`.
(enum Lisp_Compiled): Use `CLOSURE_` prefix i.s.o `COMPILED_`.
Also use `CODE` rather than `BYTECODE`.
(CLOSUREP): Rename from `COMPILEDP`.
(enum Lisp_Closure): Rename from `Lisp_Compiled`.

* src/alloc.c, src/bytecode.c, src/comp.c, src/data.c, src/eval.c,
* src/fns.c, src/lisp.h, src/lread.c, src/pdumper.c, src/print.c,
* src/profiler.c: Rename all uses accordingly.
* src/.gdbinit (xclosure): Rename from `xcompiled`.
(xcompiled): New obsolete alias.
(xpr): Adjust accordingly.  Also adjust to new PVEC_CLOSURE tag name.

* src/bytecode.c (exec_byte_code):
We can safely assume that the immediate argument to varref and varset
is a bare symbol; the byte-compiler should guarantee that.
