Example of a test: F12153075: ast-dump-lambda.cpp
<https://reviews.llvm.org/F12153075>
An AST serialization dump test is a test which compares the output of
`-ast-dump` on the source and of `-ast-dump-all` on a PCH generated from the
source. Modulo a few differences the outputs should match.
This patch to `make-ast-dump-check.sh` enables automatically generating these
tests.
