Siddhesh Poyarekar 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.

Adhemerval Zanella aa630f590c PowerPC: modf optimization fix 
This patch fix the 3c0265394d 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).

Thomas Schwinge 572676160d New <math.h> macro named issignaling to check for a signaling NaN (sNaN). 
It is based on draft TS 18661 and currently enabled as a GNU extension.

Adhemerval Zanella 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.

Alan Modra 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:

Siddhesh Poyarekar 6f2e90e78f Make mantissa type of mp_no configurable 
The mantissa of mp_no is intended to take only integral values.  This
is a relatively good choice for powerpc due to its 4 fpus, but not for
other architectures, which suffer due to this choice.  This change
makes the default mantissa a long integer and allows powerpc to
override it.  Additionally, some operations have been optimized for
integer manipulation, resulting in a significant improvement in
performance.
