- Avoid redundant switch-break.
WGSL does an implicit break at the end of a switch case, because

tint.h selectively includes headers depending on what features are enabled. It
is based off of the original sample code, so should give users access to all of
the functionality demonstrated in there.
This is located in include/tint/, so that users can have a pretty include of
tint/tint.h.

Produce less noise in ASTs for a common case.
Also test that an empty continuing construct doesn't show up in the
AST. That's currently handled by the AST code. We want to keep this
behaviour even if the AST implementation changes. Right now
code change is needed when emitting the start of a continuing
construct.
