In cranelift x86 encodings, it seemed unintuitive to specialize Templates with both `infer_rex()`` and `w()`: if `w()` is specified, the REX.W bit must be set so a REX prefix is alway required--no need to infer it. This change forces us to write `rex().w()``--it's more explicit and shows more clearly what cranelift will emit. This change also modifies the tests that expected DynRex recipes.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
