042426ba63 Optimize symbol lookup 
Do not run symbol lookup on already visited soinfos
 Not taking into account already visited libraries
 dramatically slows down dlsym in cases when there
 are multiple occurrences of a large library in
 dependency tree.

72d7e667c7 Fix our x86 PIC_PROLOGUE. 
The old definition only worked for functions that didn't use numbered
local labels. Upstream uses '666' not only as some kind of BSD in-joke,
but also because there's little likelihood of any function having
labels that high.

There's a wider question about whether we actually want to go via the
PLT at all in this code, but that's a question for another day.

30214b901e Add memory ordering constraint, convert to C11 atomics 
Add an ordering constraint/fence to __system_property_serial.
This slows down a read on a Nexus 5 from about 50 to about 70 ns,
but avoids the possibility of seeing an inconsistent property value.
Use C11 atomic operations where easy and appropriate.
This code remains not fully C++11 memory model conformant, but
I would now expect the generated code to now be correct with current compilers.

ifuncs now work in i386 and x86_64 when called in the same library as
well as in a different library.
