	* pa.c (emit_move_sequence): Use cint_ok_for_move to check whether a
	constant can be loaded in a single instruction to a register.  When
	loading immediate constants, use PLUS instead of HIGH/LO_SUM.  Use
	depdi for insertion of most significant 32-bits on 64-bit hosts.
	* pa.h (LEGITIMATE_CONSTANT_P): Accept constants that can be built
	with ldil/ldo/depdi instruction sequence on 64-bit hosts.
	* pa.md: New addmove pattern for adding constant_int to HImode
	register and moving result to HImode register.  Remove HImode HIGH
	and LO_SUM patterns.
