Normalize names of some source files

Most tdep/nat files are named:

  <cpu>-<os>-tdep.c
  <cpu>-<os>-nat.c

A few files do not respect this scheme.  This patch renames them so that
they are consistent with the rest of the files.  It builds fine with
--enable-targets=all, but that doesn't test the nat files.  I can only
hope that my grep skill is good enough.

+/* The `/proc' interface divides the target machine's register set up
+   into two different sets, the general purpose register set (gregset)
+   and the floating-point register set (fpregset).  For each set,
+   there is an ioctl to get the current register set and another ioctl
+   to set the current values.
+
+   The actual structure passed through the ioctl interface is, of
+   course, naturally machine dependent, and is different for each set
+   of registers.  For the i386 for example, the general-purpose
+   register set is typically defined by:
+
+   typedef int gregset_t[19];           (in <sys/regset.h>)
+
+   #define GS   0                       (in <sys/reg.h>)
+   #define FS   1
+   ...
+   #define UESP 17
+   #define SS   18
+
+   and the floating-point set by:
+
+   typedef struct fpregset   {
+           union {
+                   struct fpchip_state            // fp extension state //
+                   {
+                           int     state[27];     // 287/387 saved state //
+                           int     status;        // status word saved at //
+                                                  // exception //
+                   } fpchip_state;
+                   struct fp_emul_space           // for emulators //
+                   {
+                           char    fp_emul[246];
+                           char    fp_epad[2];
+                   } fp_emul_space;
+                   int     f_fpregs[62];          // union of the above //
+           } fp_reg_set;
+           long            f_wregs[33];           // saved weitek state //
+   } fpregset_t;
+
+   Incidentally fpchip_state contains the FPU state in the same format
+   as used by the "fsave" instruction, and that's the only thing we
+   support here.  I don't know how the emulator stores it state.  The
+   Weitek stuff definitely isn't supported.
+
+   The routines defined here, provide the packing and unpacking of
+   gregset_t and fpregset_t formatted data.  */
