* config/rs6000/rs6000.c (rs6000_setup_reg_addr_masks): Do not set
Altivec & -16 mask if the type is not valid for Altivec registers.
(rs6000_secondary_reload_memory): Add support for ((reg + const) +
reg) that occurs during push_reload processing.
* config/rs6000/altivec.md (altivec_mov<mode>): Add instruction
alternative for moving constant vectors which are easy altivec
constants to GPRs. Set the length attribute each of the
alternatives.
