b937534868 Avoid crashing in LD_DEBUG when program name is unavailable 
Resolves: #15465

The program name may be unavailable if the user application tampers
with argc and argv[].  Some parts of the dynamic linker caters for
this while others don't, so this patch consolidates the check and
fallback into a single macro and updates all users.

aa630f590c PowerPC: modf optimization fix 
This patch fix the 3c0265394d9ffedff2b0de508602dc52e077ce5c commits
by correctly setting minimum architecture for modf PPC optimization
to power5+ instead of power5 (since only on power5+ round/ceil will
be inline to inline assembly).

3c0265394d PowerPC: modf optimization 
This patch implements modf/modff optimization for POWER by focus
on FP operations instead of relying in integer ones.

60c414c346 PowerPC: remove branch prediction from rint implementation 
The branch prediction hints is actually hurts performance in this case.
The assembly implementation make two assumptions: 1. 'fabs (x) < 2^52'
is unlikely and 2. 'x > 0.0' is unlike (if 1. is true). Since it a
general floating point function, expected input is not bounded and then
it is better to let the hardware handle the branches.

b0f1246ab4 PowerPC: .eh_frame info in crt1.o isn't useful and triggers gold bug 14675. 
The .eh_frame info in crt1.o isn't useful and this patch prevents it from
being generated on PowerPC.  It triggers the following gold bug:

15d0da8cb3 Add versions of wcscpy, wcschr, wcsrchr for power6/power7. 
Initially based on the versions found in wcsmbs/* ; these files have
been changed by hand unrolling, and adding some additional variables
to allow some read-ahead to occur, which then relieves some of the
wait-for-increment/wait-for-load/wait-for-compare-results pressure
that was slowing down every iteration through the while-loop.

For 64-bit Power7, These changes give an approx 20% throughput boost
for the wcschr and wcsrchr functions; and approx 40% boost for the
wcscpy function.  32-bit improvements appear to be slightly better
with ~ %30 and ~ %45 respectively.  Results for Power6 closely match
those for power7.

14a50c9d23 [Powerpc] Tune/optimize powerpc{32,64}/power7/memchr.S. 
Assorted tweaking, twisting and tuning to squeeze a few additional cycles
out of the memchr code.   Changes include bypassing the shift pairs
(sld,srd) when they are not required, and unrolling the small_loop that
handles short and trailing strings.

Per scrollpipe data measuring aligned strings for 64-bit, these changes
save between five and eight cycles (9-13% overall) for short strings (<32),
Longer aligned strings see slight improvement of 1-3% due to bypassing the
shifts and the instruction rearranging.
