/* Given INSN_ISA* values X and Y, where X ranges over INSN_ISA1 through
INSN_ISA5_32R2 and Y ranges over INSN_ISA1 through INSN_ISA64R2,
this table describes whether at least one of the ISAs described by X
is/are implemented by ISA Y. (Think of Y as the ISA level supported by
a particular core and X as the ISA level(s) at which a certain instruction
is defined.) The ISA(s) described by X is/are implemented by Y iff
(mips_isa_table[(Y & INSN_ISA_MASK) - 1] >> ((X & INSN_ISA_MASK) - 1)) & 1
