This patch adds support for the hyperprivileged registers %hstick_offset

and %hstick_enable to the Sparc assembler.

	* config/tc-sparc.c (hpriv_reg_table): Added entries for
	%hstick_offset and %hstick_enable.
	* doc/c-sparc.texi (Sparc-Regs): Document the %hstick_offset and
	%hstick_enable hyperprivileged registers.

	* sparc-dis.c (v9_hpriv_reg_names): Names for %hstick_offset and
	%hstick_enable added.

	* gas/sparc/rdhpr.s: Test rd %hstick_offset and %hstick_enable.
	* gas/sparc/rdhpr.d: Likewise.

	* gas/sparc/wrhpr.s: Test wr %hstick_offset and %hstick_enable.
	* gas/sparc/wrhpr.d: Likewise.
