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