* i386.md (return, return_internal, prologue, prologue_set_got,
prologue_get_pc, epilogue, leave, pop): New patterns for emitting
asm from prologue and epilogue RTL.

function_epilogue, ix86_expand_epilogue): Generate prologue and
epilogue as RTL (prior to scheduling) instead of emitting asm.
(override_options): If only -march is given, make it the default -mcpu.
