Frontend for [SPIR-V][spv] (Standard Portable Intermediate Representation).
## ID lookups
Our IR links to everything with `Handle`, while SPIR-V uses IDs.
In order to keep track of the associations, the parser has many lookup tables.
There map `spv::Word` into a specific IR handle, plus potentially a bit of
extra info, such as the related SPIR-V type ID.
TODO: would be nice to find ways that avoid looking up as much
## Inputs/Outputs
We create a private variable for each input/output. The relevant inputs are
populated at the start of an entry point. The outputs are saved at the end.
The function associated with an entry point is wrapped in another function,
such that we can handle any `Return` statements without problems.
## Row-major matrices
We don't handle them natively, since the IR only expects column majority.
Instead, we detect when such matrix is accessed in the `OpAccessChain`,
and we generate a parallel expression that loads the value, but transposed.
This value then gets used instead of `OpLoad` result later on.
