[Bug target/14619] New: Incorrect Dwarf 2 information in function prologue

["orjanf at axis dot com" <gcc-bugzilla at gcc dot gnu dot org>]

For the following example code:

000802e4 <foo>:
void foo(void) 
{
   802e4:	fce1 ee8f           	push $r8
   802e8:	6e86                	move.d $sp,$r8
}
   802ea:	68e6                	move.d $r8,$sp
   802ec:	7fb6                	ret 
   802ee:	6e8e                	pop $r8

the corresponding Dwarf 2 information is

00000038 00000014 00000010 FDE cie=00000010 pc=000802f0..00080310
  DW_CFA_advance_loc: 0 to 000802f0
  DW_CFA_def_cfa: r8 ofs 8
  DW_CFA_offset: r16 at cfa-4
  DW_CFA_offset: r8 at cfa-8

which incorrectly specifies that at 802f0 CFA is r8 + 8 and both r16 and r8 are 
saved.
