pa.h (VAL_U6_BITS_P): Define.

	* config/pa/pa.h (VAL_U6_BITS_P): Define.
	(INT_U6_BITS): Likewise.
	* config/pa/predicates.md (uint6_operand): New predicate.
	(shift5_operand, shift6_operand): Likewise.
	* config/pa/pa.md (lshrsi3, rotrsi3): Use shift5_operand instead of
	arith32_operand.
	(lshrdi3): Use shift6_operand.
	(shrpsi4, shrpdi4): New insn patterns.
	(extzv): Delete expander.
	(extzvsi, extzvdi): New expanders.  Use uint5_operand and uint6_operand
	predicates in unamed zero extract patterns.  Tighten common constraint.

	predicates in unamed insert patterns.  Tighten common constraint.
	Change uint32_operand predicate to uint6_operand predicate in unamed
	DImode pattern to insert constant values of type 1...1xxxx.
