We've previously discussed eliminating VEC_INTERLEAVE_*_EXPR, and
VEC_EXTRACT_{EVEN,ODD}_EXPR, as both have different semantics
depending on target endianness. The replacement, VEC_PERM_EXPR,
does not have this ambiguity.
In order for this to not introduce regressions in the various
targets that have previously implmented vec_interleave patterns,
we have to recognize the various vec_perm_const patterns.
To a greater or lesser degree, all of these backend patches
mirror the way that i386 approaches this problem.
Not all of the variations are completely tested; e.g. mips loongson
or powerpc paired-single. The arm patches have had some amount of
cross-testing, and are currently bootstrapping on hardware. The
ia64 patches need testing on big-endian hpux.

Richard Henderson (5):
rs6000: Implement vec_perm_constv16qi for altivec.
ia64: Implement vec_perm_const.
rs6000: Cleanup interleave/even_odd/vec_perm.
mips: Implement vec_perm_const.
arm: Implement vec_perm and vec_perm_const for NEON.
jakub (1):
Delete VEC_INTERLEAVE_*_EXPR.
