There is an external assembly declaration extension in GNU C that glibc
uses when building with ieee128 floating point support on ppc64le.
Marking that as volatile makes no sense, so the build breaks.
It does not make sense to only mark this as volatile on Linux, since if
do not want the compiler reordering things on Linux, we do not want the
compiler reordering things on any other platform, so we stop treating
Linux specially and just manually inline the CPP macro so that we can
eliminate it. This should fix the build on ppc64le.

* Cast void * to uintptr_t before casting to boolean_t.
* Avoid clashing definition of __asm when not on Linux to
prevent duplicate __volatile__. This was already done in
some places but not all.

Implements the RAID-Z function using AltiVec SIMD.
This is basically the NEON code translated to AltiVec.
Note that the 'fletcher' algorithm requires 64-bits
operations, and the initial implementations of AltiVec
(PPC74xx a.k.a. G4, PPC970 a.k.a. G5) only has up to
32-bits operations, so no 'fletcher'.
