The OpenGL ES 3.1 spec says:
"The point size is taken from the shader built-in gl_PointSize written by the vertex shader, and clamped to the implementation-dependent point size range. If the value written to gl_PointSize is less than or equal to zero, or if no value is written, the point size is undefined."
ANGLE/D3D11 will emit a warning on this and abort processing, causing dawn_end2end tests to fail.

The current presubmit has the filter inverted so it would only attempt
to match the filtered files. The file name also has to be converted to
`LocalPath` otherwise it's attempting to compare a python object to a
string and always fails to match.

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 {} \;
```

Implement new transform UnwindDiscardFunctions that replaces discard
statements with setting a module-level bool, adds a check and return for
this bool after every function call that may discard, and finally
invokes a single function that executes a discard from top-level
functions.
Regenerated tests and remove HLSL ones that used to fail FXC because it
had difficulty with discard.

Use of semicolons is still supported, but deprecated.
Also updates the parsing methods for structures to better match the

In GLSL, runtime-sized arrays are only valid in interface blocks, not
in structs. The existing code was attempting to avoid emitting structs
containing runtime-sized arrays but was confused by type aliases in
the AST resulting in arrays being missed.
The fix is to do the work on the semantic types instead, where type
aliases have been resolved.

While Desktop GLSL supports the Coarse and Fine flavours, GLSL ES does
not. For now, emit dFdx/dFdy in all cases for ES, but excluding the
Coarse and Fine flavours via validation is also an option.

The multiplanar external texture transform has been integrated into
Dawn, which means we have no use for the single plane transform - so it
