Previously, a preamble only included #if blocks (and friends like
ifdef) if there was a corresponding #endif before any declaration or
definition. The problem is that any header file that uses include guards
will not have a preamble generated, which can make code-completion very
slow.
To prevent errors about unbalanced preprocessor conditionals in the
preamble, and unbalanced preprocessor conditionals after a preamble
containing unfinished conditionals, the conditional stack is stored
in the pch file.
This fixes PR26045.

The failing was due to this:
1. preamble.c contains CR+LF new lines
2. write() is called with a buffer containing the original (CR+LF) to output the result on the console.
3. In text mode(the default), write() convert LF to CR+LF even if LF is preceded by CR, hence we have CR+CR+LF which filecheck interprets as 2 lines.

which is the part of the file that contains all of the initial
comments, includes, and preprocessor directives that occur before any
of the actual code. Added a new -print-preamble cc1 action that is
only used for testing.
