that in the UNW_LOCAL_ONLY-case, bit 2 in register save locations is unused. If
UNW_LOCAL_ONLY is defined, define stream-lined versions of IA64_REG_LOC(),
IA64_FPREG_LOC(), ia64_acquire_unwind_info(), ia64_release_unwind_info(), ia64_get(),
ia64_put(), ia64_getfp(), and ia64_putfp(). Drop convenience macros and declarations for
ia64_glibc_{acquire,release}_unwind_info(). Add convenience macro and declaration for
ia64_local_resume().

Call abort() instead of fprintf() when encountering a signal trampoline.
(unw_init_local): Initialize uc->sc_rbs_base to the bsp value of the current function.
For UNW_LOCAL_ONLY case, just initialize c->uc and then call
common_init() to do the remaining initialization. For the general case,
just initialize the accessor and then also call common_init().
