This CL renames the attributes to store `expr` instead of `value`.
This closer matches what is stored.

This CL updates the internal storage for a `@location` attribute
to store the `Expression` instead of a raw `uint32_t`. The current
parser is updated to generate an `IntLiteralExpression` so we still
parse as a `uint32_t` at the moment.

Add a 'NodeID' to each ast::Node which is the sequentially allocated
index of the node. Use this in sem::Info to map the AST node to the
semantic node, instead of using a std::unordered_map.
Optimised very hot code by entirely eliminating map lookups, and
dramatically reducing cache misses (lookups are usually sequentually
ordered).

Tint makes heavy use of RTTI via virtual methods. Give the compiler the
opportunity to optimize away some of these virtuals.
