At some point arm moved to a unified syntax for arm and thumb instructions.

While binutils supports both "unified" and "divided" syntax (defaulting
to divided) the integrated assembler in clang only supports unified names
so switch some files to unified syntax.  Similiar changes were made in
bitrig and freebsd.  No difference in objdump -d output.

tested on zaurus by deraadt@, ok miod@
