PR libstdc++/87194 fix range insertion into maps and sets
Since C++11 range insertion and construction of maps and sets from a
pair of iterators only requires that the iterator's value_type is
convertible to the container's value_type (previously it had to be the
same).
This fixes the implementation to meet that relaxed requirement, by
defining a pair of overloads that either insert or emplace, depending on
the iterator's value_type. Instead of adding yet another overload of
_M_insert_unique and _M_insert_equal, the overloads taking iterators are
renamed to _M_insert_range_unique and _M_insert_range_equal.

fixincludes: vxworks: remove unnecessary parentheses in ioctl wrapper macro
The rationale for the fixinclude ioctl macro wrapper is, as far as I can
tell (https://gcc.gnu.org/ml/gcc-patches/2012-09/msg01619.html)
Fix 2: Add hack for ioctl() on VxWorks.
ioctl() is supposed to be variadic, but VxWorks only has a three
argument version with the third argument of type int. This messes up
when the third argument is not implicitly convertible to int. This
adds a macro which wraps around ioctl() and explicitly casts the third
argument to an int. This way, the most common use case of ioctl (with
a const char * for the third argument) will compile in C++, where
pointers must be explicitly casted to int.
However, we have existing C++ code that calls the ioctl function via
::ioctl(foo, bar, baz)
and obviously this breaks when it gets expanded to
::(ioctl)(foo, bar, (int)(baz))
Since the GNU C preprocessor already prevents recursive expansion of
function-like macros, the parentheses around ioctl are unnecessary.
Incidentally, there is also a macro sioIoctl() in the vxworks sioLib.h
header that expands to
((pSioChan)->pDrvFuncs->ioctl (pSioChan, cmd, arg))
which also breaks when that gets further expanded to
((pSioChan)->pDrvFuncs->(ioctl) (pSioChan, cmd, (int)(arg)))
This patch partly fixes that issue as well, but the third argument to
the pDrvFuncs->ioctl method should be void*, so the cast to (int) is
slightly annoying. Internally, we've simply patched the sioIoctl macro:
(((pSioChan)->pDrvFuncs->ioctl) (pSioChan, cmd, arg))

Limit movmem copies to TImode on AArch64
On AArch64 we have integer modes larger than TImode, and while we can generate
moves for these they're not as efficient.
So instead make sure we limit the maximum we can copy to TImode. This means
copying a 16 byte struct will issue 1 TImode copy, which will be done using a
single STP as we expect but an CImode sized copy won't issue CImode operations.
I am also moving the residual code inside the if since smallest_mode_for_int may
trap if the mode doesn't exist. And the only time we know the mode to exist for
sure is when the condition of the if is true. This also saves repeated calls to
the iterator.

C++: underline param in print_conversion_rejection (more PR c++/85110)
Consider this bogus code (from g++.dg/diagnostic/param-type-mismatch-2.C):
struct s4 { static int member_1 (int one, const char **two, float three); };
int test_4 (int first, const char *second, float third)
{
return s4::member_1 (first, second, third);
}
Before this patch, g++ emits:
demo.cc: In function 'int test_4(int, const char*, float)':
demo.cc:5:44: error: no matching function for call to 's4::member_1(int&, const char*&, float&)'
5 | return s4::member_1 (first, second, third);

| ^~~~~~~~
demo.cc:1:24: note: no known conversion for argument 2 from 'const char*' to 'const char**'
With this patch, it highlights the pertinent parameter in the
"no known conversion" note:

This is the gofrontend version of https://golang.org/cl/91796.
This is part of that CL, just the compiler change and required runtime
changes, in preparation for updating libgo to 1.11.
Relevant part of original CL description:
The hmap field in the maptype is only used by the runtime to check the sizes of
the hmap structure created by the compiler and runtime agree.
Comments are already present about the hmap structure definitions in the
compiler and runtime needing to be in sync.
