This patch adds a macro that extracts the TYPE_MODE and forcibly
converts it to a scalar_float_mode. The forcible conversion
includes a gcc_checking_assert that the mode is a SCALAR_FLOAT_MODE_P.
This becomes important as more static type checking is added by
later patches. It has the additional benefit of bypassing the
VECTOR_TYPE_P (...) ? vector_type_mode (...) : ... condition
in TYPE_MODE; in release builds the new macro is a simple
field access.

The new iterators are:
- FOR_EACH_MODE_IN_CLASS: iterate over all the modes in a mode class.
- FOR_EACH_MODE_FROM: iterate over all the modes in a class,
starting at a given mode.
- FOR_EACH_WIDER_MODE: iterate over all the modes in a class,
starting at the next widest mode after a given mode.
- FOR_EACH_2XWIDER_MODE: same, but considering only modes that
are two times wider than the previous mode.
- FOR_EACH_MODE_UNTIL: iterate over all the modes in a class until
a given mode is reached.
- FOR_EACH_MODE: iterate over all the modes in a class between
two given modes, inclusive of the first but not the second.
These help with the stronger type checking added by later patches,
since every new mode will be in the same class as the previous one.

__atomic_add_fetch adds a value to some memory, and returns the result.
If there is no direct support for this, expand_builtin_atomic_fetch_op
is asked to implement this as __atomic_fetch_add (which returns the
original value of the mem), followed by the addition. Now, the
__atomic_add_fetch could have been a tail call, but we shouldn't
perform the __atomic_fetch_add as a tail call: following code would
not be executed, and in fact thrown away because there is a barrier
after tail calls.
This fixes it.

The __builtin_isinf_sign folding uses a type-specific signbit built-in
function, meaning it only works for the types float, double and long
double, not for types such as _FloatN, _FloatNx, __float128. Since
the signbit built-in function is now type-generic, that can be used
unconditionally, much as the code uses the type-generic isinf built-in
function unconditionally, and this patch makes it do so, thereby
enabling __builtin_isinf_sign (which glibc uses to expand the isinf
macro since that macro in glibc traditionally provided the stronger
guarantees about the return value given by __builtin_isinf_sign) to
work for all floating-point types.
The test gcc.dg/torture/builtin-isinf_sign-1.c needs updating because
it tests that comparisons of calls to __builtin_isinf_sign to
conditional expressions involving __builtin_isinf and
__builtin_signbit* get optimized away, and with a change of what
particular built-in function for signbit is used, GCC doesn't notice
the expressions with type-generic and non-type-generic built-in
functions are equivalent at -O0 or -O1 (it does optimize away the
original test at -O2).
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

This patch adds a minimal set of built-in functions for the new
_FloatN and _FloatNx types.
The functions added are __builtin_fabs*, __builtin_copysign*,
__builtin_huge_val*, __builtin_inf*, __builtin_nan* and
__builtin_nans* (where * = fN or fNx). That is, 42 new entries are
added to the enum of built-in functions and the associated array of
decls, where not all of them are actually supported on any one target.
These functions are believed to be sufficient for libgcc (complex
multiplication and division use __builtin_huge_val*,
__builtin_copysign* and __builtin_fabs*) and for glibc (which also
depends on complex multiplication from libgcc, as well as using such
functions itself). The basic target-independent support for folding /
expanding calls to these built-in functions is wired up, so those for
constants can be used in static initializers, and the fabs and
copysign built-ins can always be expanded to bit-manipulation inline
(for any format setting signbit_ro and signbit_rw, which covers all
formats supported for _FloatN and _FloatNx), although insn patterns
for fabs (abs<mode>2) and copysign (copysign<mode>3) will be used when
available and may result in more optimal code.
The complex multiplication and division functions in libgcc rely on
predefined macros (defined with -fbuilding-libgcc) to say what the
built-in function suffixes to use with a particular mode are. This
patch updates that code accordingly, where previously it involved a
hack supposing that machine-specific suffixes for constants were also
suffixes for built-in functions.
As with the main _FloatN / _FloatNx patch, this patch does not update
code dealing only with optimizations that currently has cases only
covering float, double and long double, though some such cases are
straightforward and may be covered in a followup patch.
The functions are defined with DEF_GCC_BUILTIN, so calls to the TS
18661-3 functions such as fabsf128 and copysignf128, without the
__builtin_, will not be optimized. As noted in the original _FloatN /
_FloatNx patch submission, in principle the bulk of the libm functions
that have built-in versions should have those versions extended to
cover the new types, but that would require more consideration of the
effects of increasing the size of the enum and initializing many more
functions at startup.
I don't know whether target-specific built-in functions can readily be
made into aliases for target-independent functions, but if they can,
it would make sense to do so for the x86, ia64 and rs6000 *q functions
corresponding to these, so that they can benefit from the
architecture-independent folding logic and from any optimizations
enabled for these functions in future, and so that less
target-specific code is needed to support them.
