Currently the high-level xor code chunks up all operations into small
units for only up to 1 + 4 vectors, and passes it to four different
methods. This means the FPU/vector context is entered and left a lot for
wide stripes, and a lot of indirect expensive indirect calls are
performed. Switch to passing the entire gen_xor request to the low-level
ops, and provide a macro to dispatch it to the existing helper.
This reduce the number of indirect calls and FPU/vector context switches
by a factor approaching nr_stripes / 4, and also reduces source and binary
code size.

xor_blocks is very annoying to use, because it is limited to 4 + 1 sources
/ destinations, has an odd argument order and is completely undocumented.
Lift the code that loops around it from btrfs and async_tx/async_xor into
common code under the name xor_gen and properly document it.

Move the asm/xor.h headers to lib/raid/xor/$(SRCARCH)/xor_arch.h and
include/linux/raid/xor_impl.h to lib/raid/xor/xor_impl.h so that the
xor.ko module implementation is self-contained in lib/raid/.
As this remove the asm-generic mechanism a new kconfig symbol is added to
indicate that a architecture-specific implementations exists, and
xor_arch.h should be included.

Drop the pretty confusing historic XOR_TRY_TEMPLATES and
XOR_SELECT_TEMPLATE, and instead let the architectures provide a
arch_xor_init that calls either xor_register to register candidates or
xor_force to force a specific implementation.

Keep xor.h for the public API, and split the struct xor_block_template
definition that is only needed by the xor.ko core and
architecture-specific optimizations into a separate xor_impl.h header.

Originally, the XOR code benchmarked all algorithms at load time, but it
has since then been hacked multiple times to allow forcing an algorithm,
and then commit 524ccdbdfb52 ("crypto: xor - defer load time benchmark to
a later time") changed the logic to a two-step process or registration and
benchmarking, but only when built-in.
Rework this, so that the XOR_TRY_TEMPLATES macro magic now always just
deals with adding the templates to the list, and benchmarking is always
done in a second pass; for modular builds from module_init, and for the
built-in case using a separate init call level.
