The goal is to get some initial CacheIR to MIR compilation working for a simple IC (maybe GetName or UnaryArith..). There will definitely be missing pieces but it's good to have something concrete we can improve and extend.

The transpiler lets us inline CacheIR IC stubs for JSOp::Get{G}Name ops.
It supports just enough instructions to pass jit-tests.
There are still missing pieces (see TODOs, especially in WarpOracle::maybeInlineIC)
and ideally the transpiler class should share more code with CacheIRCompiler
(for example the reader.readFoo() calls).
