Currently building gcc for xtensa configuration with XCHAL_HAVE_LOOPS
set to 0 fails with the following error:
xtensa.c:3952: undefined reference to `reorg_loops(bool, hw_doloop_hooks*)'
Only compile target-specific zero-overhead loop optimization code when
TARGET_LOOPS allows it.

* config/xtensa/xtensa.c (hwloop_optimize, hwloop_fail,
hwloop_pattern_reg, xtensa_doloop_hooks, xtensa_reorg_loops):
put under #if TARGET_LOOPS guard.
