Subject: m32c.c (m32c_emit_epilogue): Don't try to push registers if we
 already know there aren't any.

* config/m32c/m32c.c (m32c_emit_epilogue): Don't try to push
registers if we already know there aren't any.
(m32c_emit_epilogue): Don't emit a barrier here.
(m32c_emit_eh_epilogue): Likewise.
* config/m32c/blkmov.md (movstr): Don't fail on wrong-type
operands at expand time.
* config/m32c/m32c.h (WCHAR_TYPE_SIZE): Change to 4 to match "long
int" wchar type.
(REG_CLASS_CONTENTS, reg_class, REG_CLASS_NAMES): Remove
duplicates.  Provide aliases instead.
* config/m32c/prologue.md (eh_return): Emit a barrier here.
(eh_epilogue): Add a "(return)" here as a hint to other parts of
the compiler.
