Use ptid from regcache in almost all remaining nat files

Browse source 
This patch contains almost all of the remaining changes needed to make
to_fetch_registers/to_store_registers/to_prepare_to_store independent of
inferior_ptid.  It contains only some "trivial" changes, the more
complicated ones are in separate patches.

gdb/ChangeLog:

	* i386-linux-nat.c (fetch_register, store_register,
	i386_linux_fetch_inferior_registers,
	i386_linux_store_inferior_registers): Use ptid from regcache.
	* ia64-linux-nat.c (ia64_linux_fetch_register,
	ia64_linux_store_register): Likewise.
	* inf-ptrace.c (inf_ptrace_fetch_register,
	inf_ptrace_store_register): Likewise.
