Subject: Add toolchain for riscv (ia ic il) and riscv64 (ja jc jl)

Because the rv64 ISA is very nearly a proper superset of rv32, the
compilers ic and jc are actually the same program, which compiles
to .i or .j depending on how it is invoked; similarly for ia/ja and
il/jl. It is also possible to invoke ia/ic/il with a '-j' option to
specify 64-bit behaviour.
