This removed a checking snippet which accidentally was left in in commit
r13-2446-g938cda536019cd6a1bc0dd2346381185b420bbf8 ; this caused

The following patch implements part of the OpenMP 5.2 changes related
to ordered loops and with the assumed resolution of
https://github.com/OpenMP/spec/issues/3302 issues.
The changes are:
1) the depend clause on stand-alone ordered constructs has been renamed
to doacross (because depend clause has different syntax on other
constructs) with some syntax changes below, depend clause is deprecated
(we'll deprecate stuff on the GCC side only when we have everything else
from 5.2 implemented)
depend(source) -> doacross(source:) or doacross(source:omp_cur_iteration)
depend(sink:vec) -> doacross(sink:vec) (where vec has the same syntax
as before)
2) in 5.1 and before it has been significant whether ordered clause has or
doesn't have an argument, if it didn't, only block-associated ordered
could appear in the body, if it did, only stand-alone ordered could appear
in the body, all loops had to be perfectly nested, no associated
range-based for loops, no linear clause on work-sharing loop and ordered
clause with an argument wasn't allowed on composite for simd.
In 5.2, whether ordered clause has or doesn't have an argument is
insignificant (except for bugs in the standard, #3302 mentions those),
if the argument is missing, it is simply treated as equal to collapse
argument (if any, otherwise 1). The implementation better should be able
to differentiate between ordered and doacross loops at compile time
which previously was through the absence or presence of the argument,
now it is done through looking at the body of the construct lexically
and looking for stand-alone ordered constructs. If there are any,
it is to be handled as doacross loop, otherwise it is ordered loop
(but in that case ordered argument if present must be equal to collapse
argument - 5.2 says instead it must be one, but that is clearly wrong
and mentioned in #3302) - stand-alone ordered constructs must appear
lexically in the body (and had to before as well). For the restrictions
mentioned above, the for simd restriction is gone (stand-alone ordered
can't appear in simd construct, so that is enough), and the other rules
are expected to be changed into something related to presence of
stand-alone ordered constructs in the body
3) 5.2 allows a new syntax, doacross(sink:omp_cur_iteration-1), which
means wait for previous iteration in the iteration space of all the
associated loops
The following patch implements that, except that we sorry for now
on the doacross(sink:omp_cur_iteration-1) syntax during omp expansion
because library side isn't done yet for it. It doesn't implement it for
the Fortran FE either.
Incrementally, I'd like to change the way we differentiate between
stand-alone and block-associated ordered constructs, because the current
way of looking for presence of doacross clause doesn't work well if those
clauses are removed because they had been invalid (wrong syntax or
unknown variables in it etc.) and of course implement
doacross(sink:omp_cur_iteration-1).

The following patch implements a new builtin, __builtin_issignaling,
which can be used to implement the ISO/IEC TS 18661-1 issignaling
macro.
It is implemented as type-generic function, so there is just one
builtin, not many with various suffixes.
This patch doesn't address PR56831 nor PR58416, but I think compared to
using glibc issignaling macro could make some cases better (as
the builtin is expanded always inline and for SFmode/DFmode just
reinterprets a memory or pseudo register as SImode/DImode, so could
avoid some raising of exception + turning sNaN into qNaN before the
builtin can analyze it).
For floading point modes that do not have NaNs it will return 0,
otherwise I've tried to implement this for all the other supported
real formats.
It handles both the MIPS/PA floats where a sNaN has the mantissa
MSB set and the rest where a sNaN has it cleared, with the exception
of format which are known never to be in the MIPS/PA form.
The MIPS/PA floats are handled using a test like
(x & mask) == mask,
the other usually as
((x ^ bit) & mask) > val
where bit, mask and val are some constants.
IBM double double is done by doing DFmode test on the most significant
half, and Intel/Motorola extended (12 or 16 bytes) and IEEE quad are
handled by extracting 32-bit/16-bit words or 64-bit parts from the
value and testing those.
On x86, XFmode is handled by a special optab so that even pseudo numbers
are considered signaling, like in glibc and like the i386 specific testcase
tests.

As discussed earlier, all other -static-lib* options are Driver only,
these 2 are Driver in common.opt and Fortran in lang.opt.
The spec files never pass the -static-lib* options down to any compiler
(f951 etc.), so the 2 errors below are reported only when one
runs ./f951 -static-libgfortran by hand.
The following patch just removes f951 support of these options, the
gfortran driver behavior remains as before. For other -static-lib*
option (and even these because it is never passed to f951) we never
error if we can't support those options, and e.g. Darwin is actually
able to handle those options through other means.

The following patch is a revival of the
https://gcc.gnu.org/legacy-ml/gcc-patches/2014-10/msg00771.html
patch. While trunk configured against recent glibc and with linker
--as-needed support doesn't really need to link against -lquadmath
anymore, there are still other targets where libquadmath is still in
use.
As has been discussed, making -static-libgfortran imply statically
linking both libgfortran and libquadmath is undesirable because of
the significant licensing differences between the 2 libraries.
Compared to the 2014 patch, this one doesn't handle -lquadmath
addition in the driver, which to me looks incorrect, libgfortran
configure determines where in libgfortran.spec -lquadmath should
be present if at all and with what it should be wrapped, but
analyzes gfortran -### -static-libgfortran stderr and based on
that figures out what gcc/configure.ac determined.
