James Price a89ff5981b tint: Show where control flow became non-uniform
Add additional nodes to capture places where control flow is changed
(if, switch, for, short-circuiting op, function call), and use these
to show the actual point at which control flow became non-uniform as a
result of a non-uniform value.

Do this recursively, to capture cases where control flow becomes
non-uniform after a function call statement.

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.

Ben Clayton 4d36557bce Normalize all line endings to LF
And force shader code to always use LF endings.

Post merge, there were a number of files that crept in with CRLF endings.

Some Tint end-to-end tests take objection to CRLF endings.

CRLF endings can be detected with:

```
git grep -I --files-with-matches --perl-regexp '\r' HEAD
```

And fixed with:

```
find . -type f -exec dos2unix {} \;
```

James Price 3b671cb377 wgsl: Separate struct members with commas
Use of semicolons is still supported, but deprecated.

Also updates the parsing methods for structures to better match the
WGSL grammar.
