e1c0171b2c Define register banks.
Add a RegBank class for describing CPU register banks.

Define register banks for all the ISA stubs. The ARM32 floating point
bank in particular requires attention.

Make sure we run doctests on these functions.

34f7b93482 Add stubs for Intel and ARM architectures.
The Intel ISA handles both 32-bit and 64-bit code.

ARM is split into separate arm32 and arm64 ISAs since the architectures
have little in common in instruction encodings and register files.

59eef69a4f Emit type arguments to builder methods that need it.
Use the inferred type variables to construct a type argument for builder
methods. This is for those instructions where the result types cannot be
computed from the result types.

68c9f20b77 Infer type constraints on patterns.
Each instruction used in a pattern has constraints on the types of its
operands. These constraints are expressed as symbolic type variables.

Compute type variables for each variable used in a transformation
pattern. Some are free type variables, and some are derived from the
free type variables.

The type variables associated with variables can be used for computing
the result types of replacement instructions that don't support simple
forward type inference from their inputs.

The type sets computed by this patch are conservatively too large, so
they can't yet be used to type check patterns.

38f4b9a7c8 Add a TypeVar.constrain_types() function.
This reduces the set of types a type variable can assume.

This implementation is not complete yet, so it may yield type sets that
are too large.

d22541dfa2 Add TypeVar.derived() function.

TypeVar.derived() static method which creates a derived TypeVar.

variables.

5e75b22c01 Assign a type variable to all VALUE operands.
A few operands have a fixed type assigned. Create a singleton type
variable for these exceptions. Most instructions are polymorphic, so
this is a little overhead.

Eliminate the Operand.typ field and replace it with an Operand.typevar
field which is always a TypeVar, but which only exists in VALUE
operands.
