c++: Fix return type deduction during satisfaction
During satisfaction that's entered through the three-parameter version
of satisfy_declaration_constraints, current_function_decl gets set to
the dependent DECL_TEMPLATE_RESULT for sake of access checking. This
makes the predicate in_template_function return true during satisfaction
from this entrypoint, which in turn makes calls to mark_used exit early
before it does its full processing. This leads to us accepting the
invalid testcase below due to mark_used never attempting to deduce the
return type of A::foo() and detecting failure thereof.
It seems wrong for in_template_function to be true during instantiation
or during satisfaction, so this patch makes in_template_function inspect

i386: Fix up -march=x86-64-v[234] vs. target attribute [PR98274]
The following testcase fails to compile. The problem is that
when ix86_option_override_internal is called the first time for command
line, it sees -mtune= wasn't present on the command line and so as fallback
sets ix86_tune_string to ix86_arch_string value ("x86-64-v2"), but
ix86_tune_specified is false, so we don't find the tuning in the table
but don't error on it.
When processing the target attribute, ix86_tune_string is what
it was earlier left with, but this time ix86_tune_specified is true and
so we error on it.
The following patch does what is done already e.g. for "x86-64" march,
in particular default the tuning to "generic".

i386: Make -march=x86-64-v[234] behave more like other -march= options
If somebody has -march=x86-64-v2 (or -v3 or -v4) in $CFLAGS, $CXXFLAGS etc.,
then -m32 or -mabi=ms stops working.
What is worse, if one configures gcc --with-arch-64=x86-64-v2 (or -v3 or -v4),
then -mabi=ms stops working.
I think that is a nightmare user experience. It is ok that x86-64-v[234]
behave slightly different from other -march= options (in that they imply
unless overridden -mtune=generic rather then -mtune= equal to the -march
argument), but the error when one mixes it with -mabi=ms, or -m32 doesn't
improve anything.
It is true that the exact option set is only defined in the x86-64 psABI
(IMHO that is a mistake too, we should copy that into the GCC documentation
like we document it for any other -march= option), but there is no reason
why that exact set of CPU features can't be used for other ABIs, it is just
a set of CPU features. If we add micro-architecture levels to the 32-bit
ABI (I doubt anyone wants to do that, but just hypothetically), then those
micro-architecture levels wouldn't certainly be called x86-64-v* but perhaps
i386-v*.
In the tests, __GCC_HAVE_SYNC_COMPARE_AND_SWAP_16 can't be expected on -m32
not because the CPU feature wouldn't be set, but because the instruction
is 64-bit only and 32-bit code doesn't have __int128 etc. support.

AArch64: Add support for --with-tune
Add support for --with-tune. Like --with-cpu and --with-arch, the argument is
validated and transformed into a -mtune option to be processed like any other
command-line option. --with-tune has no effect if a -mcpu or -mtune option
is used. The validating code didn't allow --with-cpu=native, so explicitly
allow that.
