bf425680e4 Let the compiler worry about implementing ffs(3).
It does at least as good a job as our old hand-written assembly anyway.

2a0b873065 Fix __errno for LP64 and clean up __get_tls.
If __get_tls has the right type, a lot of confusing casting can disappear.

It was probably a mistake that __get_tls was exposed as a function for mips
and x86 (but not arm), so let's (a) ensure that the __get_tls function
always matches the macro, (b) that we have the function for arm too, and
(c) that we don't have the function for any 64-bit architecture.

7e841ed688 Remove useless x86 fallbacks.
The NDK ABI requires that you support SSE2, and the build system won't let you
build with ARCH_X86_HAVE_SSE2 set to false. So let's stop pretending this
constant is actually a variable, and let's remove the corresponding dead code.

Also, the USE_SSE2 and USE_SSE3 macros are unused, so let's not bother
setting them.

3c4b50fd8c Fix strchr for basic non-sse case on x86
Fix source location. Move declaration of __strchr_chk out of
ifdef __BIONIC_FORTIFY which should be available for strchr.cpp
compilation when __BIONIC_FORTIFY is not defined.

baa91f4f89 Add ssse3 implementation of __memcmp16.
__memcmp16 was missing in x86. Also added C-version for backward
compatibility. Added bionic test for __memcmp16 and for wmemcmp.

04954a43b3 Break bionic implementations into arch versions.
Move arch specific code for arm, mips, x86 into separate
makefiles.
In addition, add different arm cpu versions of memcpy/memset.

Bug: 8005082

Merge from internal master (acdde8c1cf).
