[AArch64] Handle literal pools for functions > 1 MiB in size.
This patch fixes the issue in PR63304 where we have
functions that are > 1MiB. The idea is to use adrp / ldr or adrp / add
instructions to address the literal pools under the use of a command line
option. I would like to turn this on by default on trunk but keep this
disabled by default for the release branches in order to get some
serious testing for this feature while it bakes on trunk.
As a follow-up I would like to try and see if estimate_num_insns or
something else can give us a heuristic to turn this on for "large" functions.
After all the number of incidences of this are quite low in real life,
so may be we should look to restrict this use as much as possible on the
grounds that this code generation implies an extra integer register for
addressing for every floating point and vector constant and I don't think
that's great in code that already may have high register pressure.
Tested on aarch64-none-elf with no regressions. A previous
version was bootstrapped and regression tested.
Applied to trunk.

PR28901 -Wunused-variable ignores unused const initialised variables in C
12 years ago it was decided that -Wunused-variable shouldn't warn about
static const variables because some code used const static char rcsid[]
strings which were never used but wanted in the code anyway. But as the
bug points out this hides some real bugs. These days the usage of rcsids
is not very popular anymore. So this patch changes the default to warn
about unused static const variables in C with -Wunused-variable. And it
adds a new option -Wno-unused-const-variable to turn this warning off.
For C++ this new warning is off by default, since const variables can be
used as #defines in C++. New testcases for the new defaults in C and C++
are included testing the new warning and suppressing it with an unused
attribute or using -Wno-unused-const-variable.

This macro was converted to the TARGET_STRUCT_VALUE_RTX hook many years

libobjc. All the remaining definitions define the macro to 0, which
libobjc treats the same as undefined, so it won't break anything else to
have libobjc stop checking the macro. However it may be that this part
of libobjc has been broken for a long time on targets that only define
the hook, but that is a separate issue.

Stop reload1.c warning from breaking bootstrap
Some host-target combinations get bogus warnings about orig_dup
being used uninitialized. I tried to coerce the current uninit
pass to handle this case, but the patch I ended up with only worked
by accident because of the strange way in which the pass handles
limit cases. (If we have more than MAX_NUM_CHAINS chains, it silently
drops the excess chains and continues regardless, so it's quite easy
to come up with cases where the predicates for either the definition
or the use consider an arbitrary subset of the actual conditions.)
For now this patch turns -Wmaybe-uninitialized into a warning for
the affacted function. It will be a warning even if someone turns
off warnings on the command line, but I don't think that's important.
Bootstrapped and regression-tested on x86_64-linux-gnu. Also tested
with a cross-compiler to sparc-linux-gnu (which also triggered the
warning for me).
