88931983a8 Parse stack slot decls.
Add a stack slot array to repr::Function, use repr::StackSlot to reference them.

Parse stack slot declarations in the function preamble, add them to the
function.

Add a new `Context` struct which keeps track of mappings between identifiers
used in the file and real references.

615d9825e5 Simplify parser.
Use 'if let' instead of 'match' where it makes sense.

Use EBNF notation for the grammar rules. This simplifies repetition a lot.

c69a21f79e Parser for .cton files.
Recursive descent parser, although with this simple grammar there won't be any
recursion.

bbeafde243 Type::by() returns an Optional<Type>.
Don't use assertions to enforce the limits on SIMD lanes in a type, Type is too
fundamental for that. Instead, the Vector-forming by() method returns an
Optional<Type>, and None if the requested SIMD vector is not valid.

Same for Type::half_vector().

58f70ef12d Implement FromStr for Imm64, Ieee32, Ieee64.
These are bitwise exact conversions from string to immediates, implementing the
inverse of the Display trait.

Only accept hexadecimal floating point numbers to avoid issues with rounding
when converting decimal numbers to binary.

9a6f79a9ba Add some scaffolding for building more crates.
The src/tools directory contains the cretonne-tools crate which will build
binaries for testing cretonne.

provides reading and writing of .cton files.

1b7d5d849f Generate a constant hash table for recognizing opcodes.
Use a simple quadratically probed, open addressed hash table. We could use a
parfect hash function, but it would take longer to compute in Python, and this
is not in the critical path performancewise.

implementation. It allows the opcode strings to be reused by the parser.

b0c0dd1b9f Add repr.rs module containing the representation of functions.
A function owns instructions and extended basic blocks. References to these
entities are implemented as opaque structs indexing into the functions internal
tables. This avoids fighting Rust's ownership checking and it also makes
references 4 bytes on all platforms.

SSA values are identified similarly, but with an optimization for the first
value produced by an instruction. Very few instructions will produce more than
one value, and there is an extended value table for those.
