The result from parsing a function is now a DetailedFunction which
includes all comments that can be associated with an entity.
Comments before the first function are ignored, everything else is
associated with the preceeding entity.
The parse_functions() function still returns plain functions.

Export a single function: parse_functions() which results a vector of
functions parsed from the source string.
Hide the parser and lexer modules. They are not useful to external
clients.

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.
