arm: Implement ACLE Data Intrinsics
This patch implements a number of scalar data processing intrinsics from ACLE
that were requested by some users. Some of these have fast single-instruction
sequences for Armv6 and later, but even for earlier versions they can still emit
an inline sequence or a call to libgcc (and ACLE recommends them being unconditionally
available).
Chris Sidebottom wrote most of the patch, I just cleaned it up, wired up some builtins
and adjusted the tests.
Bootstrapped and tested on arm-none-linux-gnueabihf.
