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.

1e52a54a47 x86_64: Fix get_tls and statvfs
* bionic_tls.h - Add x86_64 version of get_tls macro;
* statvfs.h - 64-bit kernels don't have __statfs64/__fstatfs64, applying
workaround;

7943df62f7 Check memory size on FD_* functions
Make sure the buffer we're dealing with has enough room.
Might as well check for memory issues while we're here,
even though I don't imagine they'll happen in practice.

fc4d70fe54 Remove dead files.
memcpy.a15.S/strcmp.a15.S files were submitted by ARM for use as the basis
for the memcpy/strcmp implementations in cortex-a15.

memset.S was moved in to the generic directory.

NOTE: memcpy.a9.S was submitted by Linaro to be the basis for the memcpy
for cortex-a9/cortex-a15 but has not been incorporated yet.

Nick Kralevich
b91791d71c Use alloc_size attribute on *alloc functions
malloc and family were not declared with __attribute__((alloc_size)).
This was (sometimes) preventing FORTIFY_SOURCE related functions
from knowing the size of the buffer it's dealing with, inhibiting
FORTIFY_SOURCE protections.

Add __attribute__((alloc_size))

Information about the alloc_size attribute can be found
at http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html

5e72c513bf Remove #define _BITSIZE 32.
I've no idea what _BITSIZE was supposed to be, glibc doesn't have it,
the BSDs don't have it, and no code is currently using it. But having
it set unconditionally to 32 sounds like a bad idea.

5f6cfce4f6 Add simple implementation _Unwind_GetIP() for clang compiles.
Clang (prior to 3.4) does not actually provide a declaration (or definition)
of _Unwind_GetIP() for ARM. We can work around this by writing our own
basic implementation using the available primitive operations.

This is used to set/get TLS on x86_64. There's no public declaration

glibc (though we don't currently have any visibility controls to ensure
this).

This touches the x86 stubs too because arm, x86, and x86_64 now
all share the same header (at a source level), which causes a
reordering of the #include lines.

 - Most of the x86 syscalls are equally supported
 - *32 syscalls are not supported on 64-bit
 - *64 syscalls are replaced accordingly without 64 suffix
 - Some syscalls are not supported, replaced with x86_64 analog

Syscalls are regenerated as separate patch for review convenience.
