c1d32167dc Use dot syntax to bind type variables on instructions. 
Encodings need to refer to concrete instances of polymorphic instructions by
binding type variables. Allow dot syntax like iadd.i32 to do that.

4987282bbb Add an Encoding meta-language class. 
Start adding some RISC-V encodings too as a way of testing the ergonomics.

66f14138bb Add an EncRecipe meta-language class. 
Move the CPUMode reference from EncRecipe to the Encoding itself, allowing
EncRecipes to be shared between CPU modes. At least RISC-V should be able to
share some recipes between RV32 and RV64 modes.

82a85961ff Add PrimaryEntityData marker trait. 
Require this trait on the value type stored in an EntityMap to 'unlock' the
methods intended for primary entity maps that are allowed to create references
with the 'push method.

This prevents accidentally depending on these methods in secondary maps.

11f65fff20 Remove the cfg::predecessors_iter() method and iterator. 
This iterator enumerates all EBB references whether they are in the layout or
not. That is usually not what is needed when working with the CFG.

It is better to iterate over EBB referrences in layout order, or in reverse
post-order and then call the get_predecessors() method for each Ebb reference.

See the new implementation of print_cfg::cfg_connections().
