98624c3746 Make pthread_create report sched_setscheduler failures on LP64. 
We couldn't fix this for 32-bit because there's too much broken
code out there. (Pretty much everyone asks for real-time
scheduling for all their threads, and the kernel says "don't be
stupid".)

fbefb252b0 Modify prefetch for krait memcpy. 
I originally modified the krait mainloop prefetch from cacheline * 8 to * 2.
This causes a perf degradation for copies bigger than will fit in the cache.
Fixing this back to the original * 8. I tried other multiples, but * 8 is th
sweet spot on krait.

ac6bc31942 Remove new aligned memcpy path for cortex-a15. 
For some reason the new cortex-a15 memcpy code from ARM is really bad
for really large copies. This change forces us to go down the old path
for all copies.

All of my benchmarks show the new version is faster for large copies, but
something is going on that I don't understand.

19e62325c2 Clean up the sigprocmask/pthread_sigmask implementation. 
Let's have both use rt_sigprocmask, like in glibc. The 64-bit ABIs
can share the same code as the 32-bit ABIs.

Also, let's test the return side of these calls, not just the
setting.

6c7b3cb056 Fix clang warnings in bionic. 
This fixes a few diverse issues that clang warns on in bionic. First,
it specifies the appropriate converted types for format specifiers.
The "h" and "hh" modifiers specify that the user is passing a short or
char respectively. We were passing int deliberately in both cases and
relying on the compiler to implicitly downcast to the smaller type.
We also remove the non-standard "d" suffix from our double-precision
floating point constant. This is an extension for gcc that clang does
not implement. The third fix is to mark the c1 variable as unused,
since it truly is neither read nor written.

6e38072add Wrap sprintf()/snprintf() macros to prevent expansion errors. 
Previously, FORTIFY_SOURCE used single macros to define these standard
functions for use with clang. This can cause conflicts with other macros used
to call these functions, particularly when those macros expand the number of
arguments to the function. This change wraps our macro definitions, so that
expansion properly takes place for programmer arguments first.
