Ben Clayton 91d39a7639 tint/resolver: Reduce Hashmap fixed sizes for UA
Uniformity analysis can have very deep call stacks, and we're on the cusp of stack overflowing. Reducing these sizes helps avoid cache misses at the cost of more heap allocations.

Ben Clayton 7c6e229a18 tint/utils: Make Hashmap::Find() safer to use
Don't return a raw pointer to the map entry's value, instead return a new Reference which re-looks up the entry if the map is mutated.

James Price be656f7984 tint: Implement uniformity analaysis
This implements the uniformity analysis as currently described in the
WGSL specification. Uniformity issues are presented as warnings, and
will be switched to errors in a future release.

A follow-up patch will improve the error messages, which currently
just show the point at which a uniformity was detected.

In a future release, once we have obtained initial feedback from
users, uniformity issues will become errors.
