[commit] Fix remote debugging when DEPRECATED_REGISTER_BYTES == 0

[Daniel Jacobowitz]

As suggested by Andrew.  Checking this in, since it was his idea anyway, and
it fixes "break main; run" (as well as lots of other stuff in the testsuite
:)

	* remote.c (remote_prepare_to_store): Replace call to
	deprecated_read_register_bytes with multiple regcache_raw_read
	calls.
