C++ no-op functions can't optimize out the predicate arguments in all cases.
This was causing a problem where zero cost assertions weren't actually zero cost.
The only way to resolve this is to actually use macros sadly enough.
This will give a fairly hefty performance uplift with anything operating on IR.
This class does IR emitting and some basic handling of IR specific
tasks.
This is going to be used to split the x86 OpDispatcher from the IR
emission so the IR emitter can be passed around without caring about x86
dependencies.
