[CVS ci] switched run core

[Leopold Toetsch]

This patch adds a switched prederefed run core. It is slightly faster
then plain prederefed (no function call overhead) and ought to be the
default core, when CGoto and JIT are unavailable.

primes.pasm timings (-O3, Athlon 800, i386/linux)

slow core: 15.3
prederef: 12.8
switched: 10.6
CGoto: 9.9 (-O0)
CGP: 5.9
JIT: 3.9

Also a bug with all prederefed cores is fixed: PARROT_ARG_K was missing
from the prederef() init code.

Line 330 of ops2c.pl is producing an embedded newline in
line 4876 of core_ops_switch.c. The embedded newline causes the
build to fail on these tinderboxes:
frivolous (SUNWspro 7)
util-600

This patch resolves the problem.
