Some compilers don't support the __builtin_cpu_supports built-in,
so let's make them able to compile the project anyway.

Currently we find SSE3 and SSE4.1 code mixed togehter along with
generic code in one file. This introduces the risk that the
compiler exidantly mixes SSE4.1 instructions into an SSE3, or
even worse into a generic code path.
This commit splits the SSE3 and SSE4.1 code into separate files
and compiles them with the matching target options.

The ARM and the X86 implementation of the conversion functions share
the same, non cpu specific implementation in separate files.
This commit removes the code duplication by putting the generic
implementation into a convert_base.c, similar to to convolve_base.c

The current implementation can select the SSE support level during
compiletime only.
This commit adds functionality to automatically detect and switch
the SSE support level and automatically switch the Implementation
if the CPU does not support the required SSE level.

The non-sse implementation and the sse implementation of the convert
and convolve functions have different parameter lists. This makes it
difficult to use function pointers in order to select the right
function depending on the SSE-Level and CPU.
This commit uniformizes the parameter lists in preparation for
planned runtime cpu detection support

The compiler option -march=native instructs the compiler to auto-optimize
the code for the current build architecture. This is fine for building
and using locally, but contraproductive when generating binary packages.
This commit replaces -march=native with $(SIMD_FLAGS), which contains a
collection of supported SIMD options, so we won't loose the SSE support.

When you build from an external path, compiler can't find convert.h
include, because it was specified relative to the current directory.
Change this to specify the include dit relative to the Makefile
location.

For good practice, use const specifier when applicable.

An errant shuffle register value used in complex-complex convolution
causes distorted correlation peak-to-average values for certain TSC
values. The error effect varies for different TSC sequences with the
most noticeable effect of degraded detection on TSC 1 and no effect on
TSC 7.

Similar to the existing Intel SSE cases, add support for NEON vector
floating point SIMD processing. In this case, use ARM assembly
directly as the NEON intrinsics do not generate preferential code
output.
Currently support NEON vectorized convolution and floating point
integer conversions.

Using non-SSE4.1 enabled architecture would cause undefined
reference to 'convert_si16_ps' call.

Move x86 specific files into their own directory as this
area is about to get crowded with the addition of ARM
support.
