For error "access violation. Attempted to read from address
0x0000000000000048", added link to GitHub issue I opened. Helps to
understand what these errors are when reading the expectation files.

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 {} \;
```

Added a new transform::RemoveContinueInSwitch that replaces continue
statements in switch cases with setting a bool variable, and checking if
the variable is set after the switch to continue.

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.

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.
