- Make the Diagnostic::Level for PTH errors to be specified by the caller
clang (driver):
- Set the PTHManager diagnostic level to "Diagnostic::Error" for -include-pth
(a hard error) and Diagnostic::Warning for -token-cache (we can still
proceed).

Add a #include directive around the command line buffer so that
diagnostics generated from -include directives get diagnostics
like:
In file included from <built-in>:98:
In file included from <command line>:3:
./t.h:2:1: warning: type specifier missing, defaults to 'int'
b;

and the token after the # should be expanded if it is not a valid directive.
This allows us to transform things like:
#define FOO BAR
# FOO
into # BAR, even though FOO is not normally expanded for directives.
This should fix PR3833

diagnostics. This builds on the patch that Sebastian committed and
then revert. Major differences are:
- We don't remove or use the current ".def" files. Instead, for now,
we just make sure that we're building the ".inc" files.
- Fixed CMake makefiles to run TableGen and build the ".inc" files
when needed. Tested with both the Xcode and Makefile generators
provided by CMake, so it should be solid.
- Fixed normal makefiles to handle out-of-source builds that involve
the ".inc" files.
I'll send a separate patch to the list with Sebastian's changes that
eliminate the use of the .def files.

Redefinition checking should ignore the leading whitespace and
start of line flags on the first token of an expansion.

This prevents caret diagnostics from the scratch buffer from
including other tokens in the scratch buffer that occurred beforei
them.

This reduces # mallocs from 12444 to 11792.

themselves are.
This speeds up -Eonly cocoa.h pth by ~4%, fsyntax-only is barely measurable.

escapes in the string for subtoken positioning. This gives
us working examples like:
t.m:5:16: warning: field width should have type 'int', but argument has type 'unsigned int'
printf("\n\n%*d", (unsigned) 1, 1);
^ ~~~~~~~~~~~~
where before the caret pointed two spaces to the left.

We now emit:
t.m:6:15: warning: field width should have type 'int', but argument has type 'unsigned int'
printf(STR, (unsigned) 1, 1);
^ ~~~~~~~~~~~~
t.m:3:18: note: instantiated from:
#define STR "abc%*ddef"
^
which has the correct location in the string literal in the note line.

*end* of a macro instantiation, not the start of it. This is
really all about bug-for-bug compatibility with GCC, but not
doing this breaks the FreeBSD kernel.

Now instead of just tracking the expansion history, also track the full
range of the macro that got replaced. For object-like macros, this doesn't
change anything. For _Pragma and function-like macros, this means we track
the locations of the ')'.
This is required for PR3579 because apparently GCC uses the line of the ')'
of a function-like macro as the location to expand __LINE__ to.

a target.
Make Preprocessor.cpp define a new __INTPTR_TYPE__ macro based on this.
On linux/32, set intptr_t to int, instead of long. This fixes PR3563.

wine sources. This was happening because HighlightMacros was
calling EnterMainFile multiple times on the same preprocessor
object and getting an assert due to the new #line stuff (the
file in question was bison output with #line directives).
The fix for this is to not reenter the file. Instead,
relex the tokens in raw mode, swizzle them a bit and repreprocess
the token stream. An added bonus of this is that rewrite macros
will now hilight the macro definition as well as its uses. Woo.
