These functions match on specific patterns of shuffle that have more optimized implementations. Moving them out of instruction-selector allows us to reuse them in Liftoff. Most of these pattern matching functions do not depend on InstructionSelector, since they work on byte arrays. (The only one is CanonicalizeShuffle, which swaps node inputs.) This is only the first pass of moving those functions out. In particular we can clean things up more by moving the tests out of instruction-selector as well. Those will come in follow-up changes.

As there are not enough registers on ia32 to execute the platform- independent code, the CL also adds ia32-specific code to liftoff-compiler.cc. For this we first retrieve the memory index from the stack, do a bounds check, and calculate the final address. Only afterwards we pop all other values from the stack and pass them to the platform-dependent code.

Out of the four listed reasons, two are obsolete now, since stepping does not modify the code table any more. The first reason also cannot happen any more, since removing a breakpoint will also patch the stack of the isolate, and even if not, removing a breakpoint which is not set will have no effect (not even a stack rewriting). The same applies for the last listed reason. So overall, this code is not needed any more, since it has no effect.
