Commit: RX: Do not promote vector types

[Nick Clifton <nickc@redhat.com>]

Hi Guys,

  I am applying the patch below to the RX's handling of vector
  functions.  The RX ABI specifies that small integer return values
  should always be promoted to 32-bit values, but the code that performs
  this promotion was also affecting vector types.  This results in
  internal compiler errors when the promoted type does not match the
  original vector type.

Cheers
  Nick

	* config/rx/rx.c (rx_function_value): Do not promote vector types.
	(rx_promote_function_mode): Likewise.
	* config/rx/rx.h (LIBCALL_VALUE): Likewise.
