test suite: Add expected output for every test.

Rather than using the (munged) output of "gcc -E" we now capture
precisely the output we expect from every test case. This allows us to
stay immune from strange output from gcc (unpredictable whitespace
output---aprticularly with different gcc versions).

This will also allow us to write tests that capture expected error
messages from the preprocessor as well.
