Reuse the __is_one_of alias in additional places, and define traits to
check for signed/unsigned integer types so we don't have to duplicate
those checks elsewhere.

The additional overloads for std::byte in <bit> were reviewed by LEWG
and considered undesirable, so this patch removes them.

	* include/bits/fs_path.h (path::__is_encoded_char): Use __is_one_of.

	(log2p1(byte)): Remove.
	* include/std/charconv (__detail::__is_one_of): Move to <type_traits>.

From PowerPC ISA3.0, the description of `maddld RT, RA.RB, RC` is as follows:
64-bit RA and RB are multiplied and then the RC is signed extend to 128 bits,
and add them together.

We only apply it to 64-bit mode (DI) when implementing maddld.  However, if we
can guarantee that the result of the maddld operation will be limited to 32-bit
mode (SI), we can still apply it to 32-bit mode (SI).

    On AIX, a function has two symbols, a text symbol (with a leading dot)
    and a data one (without it).
    As the tests must be run only once, only the data symbol can be used to
    retrieve the final go symbol. Therefore, all symbols beginning with a dot
    are ignored by symtogo.

The source file rs6000.c has grown to unreasonable size and is being
split up into several smaller source files.  This should improve
compilation speed for building gcc.

This is the first of several patches to do this and moves most of the
prologue/epilogue code to a new source file.

Bootstrapped and tested on powerpc64le-unknown-linux-gnu and
powerpc64-unknown-linux-gnu with no regressions.  Is this ok for trunk?

If we have a pointer to final class, we know the dynamic type of the object
must be that class, because it can't have any derived classes.

Although libstdc++ adds 'constexpr' to its std::abs(floating-point)
overloads (as a non-conforming extension), those overloads are not used
if the target libc provides them, which is the case on Solaris.

The fix is to avoid std::abs and simply apply the negation when needed.

	* include/std/numeric (midpoint(T, T)): Avoid std::abs in constexpr
	function.
