Hi,

the attached patch removes obsolete ports (c4x, m68hc11 and ms1), toggles the 
'p' letter and adjust accordingly (only avr, fr30, m68k, mcore, rs6000 and sh 
still use define_peephole) and removes trailing spaces.

OK to commit?

Some ports are missing (lm32, moxie, nios2, nvptx, rl78, rx) so the relevant 
maintainers are CCed (see 6.3.9 Anatomy of a Target Back End in the doc).
