attempt is made to record a symbol in a discarded section, and
return `2' in that case.

constant. Same for local pointer variables.

(store_regs_kern): Rename to store_regs_kernel_thread.
(init_ops): Don't initialize ops.prepare_to_store.
(store_regs_kern): Pre-fetch register buffers from child,
because some registers may not be in the cache. Copy
regs from register cache only if they are cached.
(store_regs_lib): Copy regs from register cache only
if they are cached.
(fill_sprs32, (fill_sprs64, fill_fprs, fill_gprs32,
fill_gprs64): Ditto.
(fill_sprs64, fill_sprs32): Add selected asserts to make sure that
register sizes (from register cache) match size of buffer holding
register data.

buffer.

out of the register cache, instead of passing a pointer into
the register cache directly to ptrace. Use regcache_collect
insteaad of read_register.
(ops_prepare_to_store): Use target_read_registers instead
of read_register_bytes.
