edd81faff0 Hide __libc_malloc_dispatch. 
Now that -Bsymbolic is fixed, we can hide __libc_malloc_dispatch without
breaking ASAN.

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.

c5a13efa9b Added test for ifunc support in dynamic linker. 
ifuncs now work in i386 and x86_64 when called in the same library as
well as in a different library.

43227c0b40 Android is all-PIC/PIE. 
Clean up the x86/x86_64 assembler. The motivator (other than reducing
confusion) was that asm.h incorrectly checked PIC rather than __PIC__.
