Code that directly uses _Decimal* types on architectures not
supporting DFP is properly diagnosed ("error: decimal floating-point
not supported for this target"), via a call to
targetm.decimal_float_supported_p, if the _Decimal32, _Decimal64 or
_Decimal128 keywords are used to access it.  Use via mode attributes
is also diagnosed ("unable to emulate 'SD'"); so is use of the
FLOAT_CONST_DECIMAL64 pragma.  However, it is possible to access those
types via typeof applied to constants or built-in functions without
such an error.  I expect that there are ways to get an ICE from this;
certainly it uses a completely undefined ABI.

This patch arranges for the types not to exist in the compiler at all
when DFP is not supported.  As is done with unsupported _FloatN /
_FloatNx types, the global tree nodes are left as NULL_TREE, and the
built-in function machinery is made to use error_mark_node for them in
that case in builtin-types.def, so that the built-in functions are
unavailable.  Code handling constants is adjusted to give an error,
and other code that might not work with the global tree nodes being
NULL_TREE is also updated.

Bootstrapped with no regressions for x86_64-pc-linux-gnu.  Also tested
with no regressions for cross to aarch64-linux-gnu, as a configuration
without DFP support.

attribs.c has code to ignore all scoped attributes appertaining to
types except when they are part of the definition of that type.

I think the premise of that code is incorrect, and its presence is a
bug; such attributes are clearly valid in both C and C++, which
explicitly specify that attributes in certain syntactic positions
appertain to a particular type, only for that use of that type and not
for other uses of the same type specifiers without that attribute
specified, and while the standard attributes in C2x aren't relevant in
such contexts, some gnu:: attributes certainly are.  Where some
attributes are invalid on some types in such contexts, that's a matter
for the individual attribute handlers to diagnose (or the front end if
the requirements on a standard attribute in the standard are more
strict than those of a handler shared with a GNU attribute).

Thus, this patch removes the bogus code to allow such attributes to be
used.  Doing so (and adding tests for attributes in such positions)
shows up that the logic in the C front end for creating the
c_declarator structures for such attributes put them in the wrong
place relative to the structures for function and array types, and the
logic for postfix attributes on a list of declaration specifiers
failed to handle some cases, so those bugs are also fixed in this
patch.

This is a subsequent patch to refactor the existing float point
vector comparison operator supports.  The patch to fix PR92132
supplemented vector float point comparison by exposing the names
for unordered/ordered/uneq/ltgt and adding ungt/unge/unlt/unle/
ne.  As Segher pointed out, some patterns can be refactored
together.  The main link on this is:
