The x86 runs short on registers because numerous elements are not static.
In addition, splitting them allows more optimized code, at least for x86.

It is currently declared as a macro who is set to inlinable functions,
among which a Neon and a default C implementations.
Add a DSP parameter to each inline function, unused except by the
default C implementation which calls a function from the DSP context.
On an Arrandale CPU, gain for an inlined SSE2 function vs. a call:
- Win32: 29 to 26 cycles
- Win64: 25 to 23 cycles

arm: Remove a leftover define for the pld instruction
Merged-by: Michael Niedermayer <michaelni@gmx.at>
The function macro always sets .align 2 before declaring the
function label (since 5c5e1ea3) and always sets the section to
.text (since 278caa6a).
The .align 5 before certain functions, added in fc252eba, were added
before .text and .align were added to the function macro and thus
became useless/unused when the function macro got them.
This restores the original intention, to align the loop entry
points.

This file no longer uses the pld instruction at all, all such uses
have been split into hpeldsp_arm.S.
