220622dde5 Add libm_alias_finite for _finite symbols 
This patch adds a new macro, libm_alias_finite, to define all _finite
symbol.  It sets all _finite symbol as compat symbol based on its first
version (obtained from the definition at built generated first-versions.h).

The <fn>f128_finite symbols were introduced in GLIBC 2.26 and so need
special treatment in code that is shared between long double and float128.
It is done by adding a list, similar to internal symbol redifinition,
on sysdeps/ieee754/float128/float128_private.h.

Alpha also needs some tricky changes to ensure we still emit 2 compat
symbols for sqrt(f).

Passes buildmanyglibc.

24ab7723b8 Consistently use uintN_t not u_intN_t in libm. 
This patch changes libm code to make consistent use of C99 uintN_t
types instead of sometimes using those and sometimes using the older
nonstandard u_intN_t names.  This makes sense as a cleanup in its own
right, and also facilitates merges to GCC's libquadmath (which gets
the types from stdint.h and so may not have u_intN_t available at
all).

Tested for x86_64, and with build-many-glibcs.py.

02bbfb414f ldbl-128: Use L(x) macro for long double constants 
This runs the attached sed script against these files using
a regex which aggressively matches long double literals
when not obviously part of a comment.

Likewise, 5 digit or less integral constants are replaced
with integer constants, excepting the two cases of 0 used
in large tables, which are also the only integral values
of the form x.0*E0L encountered within these converted
files.

Likewise, -L(x) is transformed into L(-x).

Naturally, the script has a few minor hiccups which are
more clearly remedied via the attached fixup patch.  Such
hiccups include, context-sensitive promotion to a real
type, and munging constants inside harder to detect
comment blocks.

15089e046b ldbl-128: Rename 'long double' to '_Float128' 
Add a layer of macro indirection for long double files
which need to be built using another typename.  Likewise,
add the L(num) macro used in a later patch to override
real constants.

These macros are only defined through the ldbl-128
math_ldbl.h header, thereby implicitly restricting
these macros to machines which back long double
with an IEEE binary128 format.

Likewise, appropriate changes are made for the few
files which indirectly include such ldbl-128 files.

These changes produce identical binaries for s390x,
aarch64, and ppc64.
