Since ndk-build use *-gcc-ar inplace of *-ar lto plugin is called with error reads:

Symbol not found: _environ

Improve NEON instrinsics coverage from ~41% to ~93%. This change brings
new intrinsics and modifies old ones for better maintainability.
Also take into account that IA32 now supports SSSE3 by default, so we
can get rid of SSSE3 checks.

For multilib compiler x86_64-* we need to pass compiler ABI flags based on
flags -m32 or -m64, and no flags means -m64. But for 32-bit target compiler
i686-* we should pass 32-bit ABI flags only. This change fixes the last part.
