Reviewed by Mark Lam.

This patch starts using simde for find16 / find32 / find64 implementations.
And we also use a slightly different approach so that we no longer need to access to out-of-ASAN region (but still within page boundary).
So we can remove SUPPRESS_ASAN. And we also use the same code for x64 too.
