Saleem Abdulrasool 729b7d357d Lex: reduce buffer size, add a test
Reduce the stack usage as hopefully include paths are usually not too long.  Add
a test case for the path normalisation behaviour.

Ismail Pazarbasi 8d0f2f3ae3 Relax header guard mismatch warning with edit distance heuristic.
If the edit distance between the two macros is more than 50%, DefinedMacro may not be header guard or can be header guard of another header file or it might be defining something completely different set by the build environment.

Richard Smith 089ee1554c PR16339: Don't produce a diagnostic pointing at the whitespace between a '#if'
and a '!defined(X)' if we find a broken header guard. This is suboptimal; we
should point the diagnostic at the 'X' token not the 'if' token, but it fixes
the crash.

Richard Trieu 33a4b3db0d Introducing -Wheader-guard, a warning that checks header guards actually work
properly.  This warning checks that the #ifndef and #define directives at
the beginning of a header refer to the same macro name.  Includes a fix-it
hint to correct the header guard.

Daniel Dunbar cb08212fd5 tests: Use FileCheck instead of external input; I think this test was failing on
Win32 because of line ending differences.

Douglas Gregor af82e3510b 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.
