32d0fc4be5 memset replacement: unroll vectorised loops.

8a8b65d1f2 Bug 359733 amd64 implement ld.so strchr/index override like x86 
The suppression and redirection for ld.so strchr/index isn't needed for
x86. When testing a newer glibc or calling the ld.so through an alternative
path neither the suppression (doesn't match path/name) nor the redirection
(triggers too late) works. Since there is already an hardwire override for
strlen in amd64 ld.so anyway it makes sense to also hardware index (it is
always called when ld.so loads the preload images).

This was also explained in the easy hacks Fosdem session.
See https://bugs.kde.org/show_bug.cgi?id=359733 for a pointer.

5685245df0 Consistently use exit code 1 (== POSIX's EXIT_FAILURE) if things 
go wrong. As we can tell from the error messages what whent wrong 
there is no need to have different exit codes to distinguish.

bc14b1eb52 Vectorise the memcmp template implementation. For scenarios requiring 
a lot of memcmp-ing (firefox reftests) this is measurably faster.

b519f73307 Adds initial support for AArch64 (arm64) on Android. Small programs 
(/system/bin/ls, /system/bin/date) run.  Still to do:

* enable more malloc/free intercepts

* enable wrappers for ashmem and binder syscalls

* check to see if any special ioctl support is required for ARM Mali GPUs

Testcases are not compiled with -Wcast-qual.
Introduce CONST_CAST macro to work around in the few spots
where a cast that drops type qualifiers is needed.
