opcodes,gas: associate SPARC ASIs with an architecture level.

Browse Source 
With this change an architecture level bump due to assembly ASIs will show
up as a warning/error depending on options passed to gas.

Tested with sparc64-linux-gnu, and it does not introduce any regressions.

gas/ChangeLog:

	Add support for associating SPARC ASIs with an architecture level.
	* config/tc-sparc.c (parse_sparc_asi): New encode SPARC ASIs.

opcodes/ChangeLog:

	Add support for associating SPARC ASIs with an architecture level.
	* include/opcode/sparc.h (sparc_asi): New sparc_asi struct.
	* opcodes/sparc-opc.c (asi_table): Updated asi_table and encoding/
	decoding of SPARC ASIs.
