The sysdeps/ieee754/ldbl-opt version of math_ldbl_opt.h includes
math.h and math_private.h, despite not having any need for those
headers itself; the sysdeps/generic version doesn't. About 20 files
are relying on math_ldbl_opt.h to include math.h and/or math_private.h
for them, even though none of them necessarily used on a platform that
needs ldbl-opt support.

math.h or math_private.h.

libm_alias_float to define function aliases.
Tested with build-many-glibcs.py that installed stripped shared

Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes the remaining double powerpc functions use
libm_alias_double to define function aliases (with consequent removal
of the need for local compat symbol handling). Previous cleanups
avoid this patch changing installed stripped shared libraries for any
build-many-glibcs.py configuration (there are still some functions in
this patch for which the order of double and float aliases changes
within an individual source file, but in this case this doesn't result
in changes to the final library).
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged for all its hard-float powerpc configurations.

Some powerpc logb implementations define a compat symbol for logbl
based on logb, whereas libm_alias_double defines such a compat symbol
based on __logb instead. This difference (logb is weak, __logb isn't)
is enough to result in different installed stripped shared libraries.
The difference in the installed libraries isn't significant, but first
changing the compat_symbol calls helps make it possible to validate a
subsequent change to use libm_alias_double by comparison of libraries,
so this patch does such a preliminary change.
Tested with build-many-glibcs.py for all its hard-float powerpc
configurations.

1. Fix the results for negative subnormals by ignoring the signal when
normalizing the value.
2. Fix the output when the high part is a power of 2 and the low part
is a nonzero number with opposite sign. This fix is based on commit
380bd0fd2418f8988217de950f8b8ff18af0cb2b.
After applying this patch, logbl() tests pass cleanly on POWER >= 7.
Tested on powerpc, powerpc64 and powerpc64le
[BZ #21280]
* sysdeps/powerpc/power7/fpu/s_logbl.c (__logbl): Ignore the
signal of subnormals and adjust the exponent of power of 2 down
when low part has opposite sign.

The optimized POWER7 logb implementation does not use the absolute
value of the word extracted from the input to apply the leading 0-bits
builtin (to ignore the float sign). This patch fixes it by
clearing the signal bit in the resulting word.
It fixes the subnormal tests failures when running on POWER7 ou
newer chip.
Tested on powerpc64le (POWER8).
[BZ# 19375]
* sysdeps/powerpc/power7/fpu/s_logb.c (__logb): Fix return for
negative subnormals.
