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.

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.

Generate nice doc comments for the Opcode enum variants that 'cargo doc'
will pick up.
Include a `Display` trait implementation that prints the lower
snake-case version of the opcode name.

Clarify the textual encoding of floating point numbers.
Don't allow decimal floating point since conversion to/from binary can produce
rounding problems on some (buggy) systems.

Add new immediate types for floating point and vector immediates.
Use new immediates to define the constant value instructions in meta.
Split the fconst instruction into two: f32const and f64const. This prevents
confusion about the interpretation of 64 immediate bits when generating an f32
constant.
Add an immvector ImmediateType. This immediate type is variable length, and
provides all the bits of a SIMD vector directly.
