Introduce a new lexer function to compute the "preamble" of a file, 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. llvm-svn: 108913

// Preamble detection test: see below for comments and test commands.
tests: Use FileCheck instead of external input; I think this test was failing on Win32 because of line ending differences. llvm-svn: 109029
