[clang-format] Fixup #include guard indents after parseFile()

Authored by mzeren-vmw on Jan 14 2018, 7:29 AM.



When a preprocessor indent closes after the last line of normal code we do not
correctly fixup include guard indents. For example:

#ifndef HEADER_H
#define HEADER_H
#if 1
int i;
#  define A 0

incorrectly reformats to:

#ifndef HEADER_H
#define HEADER_H
#if 1
int i;
#    define A 0
#  endif

To resolve this issue we must fixup levels after parseFile(). Delaying
the fixup introduces a new state, so consolidate include guard search
state into an enum.

rebase, ping.

Looks good! Just some comments for the include guard states would be helpful.

Hm. From self review, I think this should be:

IncludeGuard = Style.IndentPPDirectives == FormatStyle::PPDIS_None ? IG_Rejected : IG_Inited;

technically I could drop the braces opened on this line. Would you like me to do that?
