Eliminate redundant loads following stores. We now have two functions `writeOpLoad` and `writeOpStore` which are in charge of writing SpvOpLoad and SpvOpStore instructions. `writeOpStore` also keeps track of pointer stores in a "store cache." Subsequent loads from that same pointer will be found in the cache and will return the value stored in that pointer instead. Such a cache definitely cannot work in the face of control flow, so we make the following concessions: - `pruneReachableOps` is now `pruneConditionalOps`. Any pointers that are altered inside a potentially-unreachable block are cleared from the cache entirely. - The entire store cache is cleared at all OpLabels within a loop. The cache also cannot work in the presence of swizzled stores, so we make another significant concession: - The entire store cache is cleared whenever we store into a non-memory pointer (e.g., assigning into a swizzled LValue, such as `foo.xz`). Despite these significant limitations, this manages to dramatically shrink many real-world examples.

Replace scalar/vector ID caches with op cache. The output changes here are almost entirely a wash, because we already had support for caching scalars and vectors. Almost all changes are just inconsequential reorderings of IDs, and the removal of RelaxedPrecision decorators on constants (which were not meaningful).

Use op cache for pointer and function types. Previously, we stringized the types and put them into fTypeMap. Using the op cache is a simpler mechanism that should work equally well. Output diffs are almost all ID reorderings. In a few cases we managed to deduplicate function types that stringize differently but come out the same in SPIR-V (e.g. no float/half distinction).
