Continuing the move to use, within libm, public names for libm
functions that can be inlined as built-in functions on many
architectures, this patch moves calls to __round functions to call the
corresponding round names instead, with asm redirection to __round
when the calls are not inlined.
An additional complication arises in
sysdeps/ieee754/ldbl-128ibm/e_expl.c, where a call to roundl, with the
result converted to int, gets converted by the compiler to call
lroundl in the case of 32-bit long, so resulting in localplt test
failures. It's logically correct to let the compiler make such an
optimization; an appropriate asm redirection of lroundl to __lroundl
is thus added to that file (it's not needed anywhere else).
Tested for x86_64, and with build-many-glibcs.py.

Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch various powerpc functions use libm_alias_double to
define function aliases (with consequent removal of the need for local
compat symbol handling). (The present patch excludes the changes to
some functions where such changes could result in differences in
installed stripped shared libraries because of changes to the exact
ordering or properties of symbols in individual .os files.)
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged for all its hard-float powerpc configurations.
