There are tons of .set assembly isa level directives in tree
to set current isa level to a higher level to enable some features.
However as nowadays MIPS is shuffling around opcodes, a single ISA
level setting may result wrong opcode in binary. We had MIPS_ISA_LEVEL
macros to determine most appropriate superset of ISA level, just do a
tree wide replacement to take advantage of those macros.
Mapping:
arch=r4000 -> MIPS_ISA_ARCH_LEVEL
{mips1, mips3, mips32r2, mips64r2} -> MIPS_ISA_LEVEL
{mips32r5, mips64r5} -> Special case for VZ, mips64r5 if target ISA
is lower than R5, otherwise MIPS_ISA_LEVEL
