The -c flag to 'cton-util filecheck' will now print out a description of how
the directives are matching the input.
This explanation is also printed when a match fails.

Use the new ISA predicate numbering to emit ISA predicate instructions in the
encoding tables.
Properly decode the ISA predicate number in RISC-V and add tests for RV32M iwth
and without 'supports_m' enabled.

Move all the byte-sized settings to the front of the byte-vector, and add a
mechanism for assigning numbers to predicates that have no name as well as
predicates from the parent settings group.
This way, all the boolean predicates that are used by a target ISA appear as a
contiguous bit-vector that is a suffix of the settings byte-vector. This
bit-vector can then be indexed linearly when resolving ISA predicates on
encodings.
Add a numbered_predicate() method to the generated Flags structs that can read
a predicate by number dynamically.

This is just the basic 'imul' the M instruction set also has mulh/mulhu which
yield the high bits of a multiplication, and there are div/rem instructions to
be implemented.
These instructions are gated by the use_m predicate, but ISA predicates are not
completely implemented yet.

Three predicates affect each extension:
- supports_m determines whether the target CPU supports the instruction set.
- enable_m determines if the instructions should be used, assuming they're
available.
- use_m is the predicate used to actually use the instructions.

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.

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.
