Log:
[rs6000] Use gen_int_mode in ieee_128bit_negative_zero

Previously we'd generate a non-canonical zero-extended CONST_INT
instead of a sign-extended one, which tripped the assert for
canonical CONST_INTs after a later patch.

gcc/
	* config/powerpcspe/powerpcspe.md (ieee_128bit_negative_zero): Use
	gen_int_mode rather than GEN_INT.
	* config/rs6000/rs6000.md (ieee_128bit_negative_zero): Likewise.
