Douglas Gregor c7d6576d54 When we parse a pragma, keep track of how that pragma was originally
spelled (#pragma, _Pragma, __pragma). In -E mode, use that information
to add appropriate newlines when translating _Pragma and __pragma into
#pragma, like GCC does. Fixes <rdar://problem/8412013>.

Douglas Gregor 127851084d Implement preprocessor code completion where a macro name is expected,
e.g., after #ifdef/#ifndef or #undef, or inside a defined <macroname>
expression in a preprocessor conditional.

Douglas Gregor 3a7ad25eb6 Introduce basic code-completion support for preprocessor directives,
e.g., after a "#" we'll suggest #if, #ifdef, etc.

Chris Lattner fb24a3a4ec push some source location information down through the compiler,
into ContentCache::getBuffer.  This allows it to produce 
diagnostics on the broken #include line instead of without a 
location.

Chris Lattner aa1cccbbef Fix PR6282: the include guard optimization cannot happen if the
guard macro is already defined for the first occurrence of the
header.  If it is, the body will be skipped and not be properly
analyzed for the include guard optimization.

Chris Lattner fde85356c6 revert my patch for rdar://7520940 that warns when a published header
is #included with "foo.h" style syntax instead of framework syntax.

Chris Lattner ed3b360290 pass the reason for failure up from MemoryBuffer and report it
in diagnostics when we fail to open a file.  This allows us to
report things like:

$ clang test.c -I.
test.c:2:10: fatal error: error opening file './foo.h': Permission denied
#include "foo.h"
         ^

Chris Lattner 710bb87147 Fix PR5633 by making the preprocessor handle the case where we can
stat a file but where mmaping it fails.  In this case, we emit an
error like:
t.c:1:10: fatal error: error opening file '../../foo.h'

instead of "cannot find file".

Chris Lattner 83bd8281e5 Fix a couple of bugs:
1. When we accept "#garbage" in asm-with-cpp mode, change the token kind
   of the # to unknown so that the preprocessor won't try to process it as
   a real #.  This fixes a crash on the attached example
2. Fix macro definition extents processing to handle #foo at the end of a
   macro to say the definition ends with the foo, not the #.

This is a follow-on fix to r72283, and rdar://6916026

Chris Lattner d66f172ab1 more fun with line markers: the digit string is required to be interpreted
as decimal, even if it starts with 0.  Also, since things like 0x1 are
completely illegal, don't even bother using numericliteralparser for them.

t.c:3:8: warning: extra tokens at end of #endif directive
#endif foo

Don't do this in strict-C89 mode because bcpl comments aren't 
valid there, and it is too much trouble to analyze whether
C block comments are safe.
