libffi PowerPC64 ELFv1 fp arg fixes
The ELFv1 ABI says: "Single precision floating point values are mapped
to the second word in a single doubleword" and also "Floating point
registers f1 through f13 are used consecutively to pass up to 13
floating point values, one member aggregates passed by value
containing a floating point value, and to pass complex floating point
values".
libffi wasn't expecting float args in the second word, and wasn't
passing one member aggregates in fp registers. This patch fixes those
problems, making use of the existing ELFv2 homogeneous aggregate
support since a one element fp struct is a special case of an
homogeneous aggregate.
I've also set a flag when returning pointers that might be used one
day. This is just a tidy since the ppc64 assembly support code
currently doesn't test FLAG_RETURNS_64BITS for integer types..

[tree-complex.c] PR tree-optimization/70291: Inline floating-point complex multiplication more aggressively
We can improve the performance of complex floating-point multiplications by inlining the expansion a bit more aggressively.
We can inline complex x = a * b as:
x = (ar*br - ai*bi) + i(ar*bi + br*ai);
if (isunordered (__real__ x, __imag__ x))
x = __muldc3 (a, b); //Or __mulsc3 for single-precision
That way the common case where no NaNs are produced we can avoid the libgcc call and fall back to the
NaN handling stuff in libgcc if either components of the expansion are NaN.
The implementation is done in expand_complex_multiplication in tree-complex.c and the above expansion
will be done when optimising for -O1 and greater and when not optimising for size.
At -O0 and -Os the single call to libgcc will be emitted.
For the code:
__complex double
foo (__complex double a, __complex double b)
{
return a * b;
}
We will now emit at -O2 for aarch64:
foo:
fmul d16, d1, d3

libgo: add type/const references to sysinfo.c
This patch adds explicit references to various types and constants
defined by the header files included by sysinfo.c (used to drive the
generation of gen-sysinfo.go as part of the libgo build via the GCC
"-fdump-go-spec" option).
The intent is to enable clients to gather the same info generated by
"-fdump-go-spec" by instead reading the generated DWARF from a
sysinfo.o object file compiled with "-g". Some compilers (notably
clang) try to omit DWARF records for a given type unless there is an
explicit use of it in the translation unit; the additional references
are to insure that everything we want to see in the DWARF shows up.

PR libstdc++/69608 Move semantics for strstreambuf
In libstdc++ the deprecated char* streams are non-copyable, as was
required pre-C++11.
Since C++11 the standard implies that those streams should be copyable,
but doesn't specify the effects of copying them. This is surely a
defect, so for consistency with other implementations this change makes
them movable, but not copyable.

Use char_span for return type of location_get_source_line
location_get_source_line returns a const char * that isn't 0-terminated,
writing back a length through an int * param.
This is error-prone, as all call-sites have to take into account the
lack of 0-termination, and respect the length of the buffer.
It's cleaner to bundle together this pointer+length state into a class,
so this patch does so, reusing the "char_span" class that I introduced
