727510f97f Add an encoding test for RISC-V.
Test that the generated encoding tables work as expected.

Change isa::Encoding into a struct with named fields so the recipe and bits can
be accessed.

662e256e3f Generate a table of encoding recipe names for each ISA.
This will be used to pretty-print encodings in the textual IR.

fc6cb2eac1 Add an isa/encoding module.
Define data types for the level 1 and level 2 hash tables. These data types are
generic over the offset integer type so they can be twice as compact for
typically small ISAs.

Use these new types when generating encoding hash tables.

Emit both level 1 and level 2 hash tables.

Define generic functions that perform lookups in the encoding tables.

Implement the TargetIsa::encode() method for RISC-V using these building
blocks.

d67bba1e85 Split the Encoding data type into two u16 values.
This hardcodes the division line between the recipe bits and the
encoding bits. It does not seem that any ISA will need more than 16 bits for
either.

dcf0b49b07 Add comments to the level2 hash tables concatenation.

Add comments to the generated output delineating the individual tables.

0357ffe670 Require a specific rustfmt version in test-all script.
Rustfmt is still so immature that developers can't have different versions
installed, or there will be minute differences in formatting causing the tests
to fail.

Only run rustfmt as part of the test-all script if the expected version is
available.

15b5576d99 Generate type numbers at meta-time.
We need to generate hash tables keyed by types, so the Python scripts need to
know the index used to represent types in Rust code.

To enforce this, add a new gen_types.py script which generates constant
definitions for the ir/types module.

Also generate constants for common SIMD vector sizes.
