Present tests for the functionality provided by command lime option
`-ast-print` check only absence of crash. This change tries to make
testing better, - the output produced by the compiler is compiled again
with option `-print-ast` and both outputs are compared. Such test at
least checks that the output is valid code. This change fixes only the
test for pure C.
This is recommit of r285882.

too low-level to actually be useful but is just interesting enough for
people to try to use it (which won't actually work beyond toy examples).
To bring back the AST printer, it needs to be:
- Complete, covering all of C/C++/Objective-C
- Documented, with appropriate Schema against which we can validate
the output
- Designed for C/C++/Objective-C, not Clang's specific ASTs
- Stable across Clang versions
- Well-tested

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

- 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious.

- AST printing, dumping, serialization, codegen.
- HTML printing.
- Parser callbacks.
Several of these are XFAIL because they trigger unimplemented code.
