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.

- set the 'StatSysCallCache' object using a setter method instead of
FileManager's constructor. This allows the cache to be installed after the
FileManager object is created.
- Add 'file mode' to FileEntry (useful for stat caching)
llvm-svn: 64351
for use by FileManager. FileManager now takes a StatSysCallCache* in its
constructor (which defaults to NULL). This will be used for evaluating whether
or not caching 'stat' system calls in PTH is a performance win. This shim adds
no observable performance impact in the case where the 'StatSysCallCache*' is
null.

- Changes Lookup*Name functions to return NamedDecls, instead of
Decls. Unfortunately my recent statement that it will simplify lot of
code, was not quite right, but it simplifies some...
- Makes MergeLookupResult SmallPtrSet instead of vector, following
Douglas suggestions.
- Adds %qN format for printing qualified names to Diagnostic.
- Avoids searching for using-directives in Scopes, which are not
DeclScope, during unqualified name lookup.

line markers, including maintenance of the virtual include stack.
For something like this:
# 42 "bar.c" 1
# 142 "bar2.c" 1
#warning zappa
# 92 "bar.c" 2
#warning gonzo
# 102 "foo.c" 2
#warning bonkta
we now produce these three warnings:
#1:
In file included from foo.c:3:
In file included from bar.c:42:
bar2.c:143:2: warning: #warning zappa
#warning zappa
^
#2:
In file included from foo.c:3:
bar.c:92:2: warning: #warning gonzo
#warning gonzo

#warning bonkta

location below it report as coming from the #line location. For example,
with:
#line 92 "foo.h"
#warning blarg!
#warning blarg!
we now emit:
foo.h:92:2: warning: #warning blarg!
#warning blarg!

foo.h:92:2: warning: #warning blarg!

makes it clear to clients that they have to pick an instantiation
or spelling location before calling it and allows optimization based
on that.

ContentCache objects to using a densemap and list, and allocating
the ContentCache objects from a bump pointer. This does not speed
up or slow down things substantially, but gives us control over
their alignment.

.def file for each library. This means that adding a diagnostic

Patch by Anders Johnsen!

as reported to the user and as manipulated by #line. This is what __FILE__,
__INCLUDE_LEVEL__, diagnostics and other things should follow (but not
dependency generation!).
This patch also includes several cleanups along the way:
- SourceLocation now has a dump method, and several other places
that did similar things now use it.
- I cleaned up some code in AnalysisConsumer, but it should probably be
simplified further now that NamedDecl is better.
- TextDiagnosticPrinter is now simplified and cleaned up a bit.
This patch is a prerequisite for #line, but does not actually provide
any #line functionality.

address space we used up. Some interesting data:
For c99-intconst-1.c:
6912762 SLocEntry's allocated, 25592386B of Sloc address space used.
For cocoa.h:
26469 SLocEntry's allocated, 10278752B of Sloc address space used.
For carbon.h:
27364 SLocEntry's allocated, 12398141B of Sloc address space used.
Clearly 2G of sloc address space should be enough for anyone?!

ground work for implementing #line, and fixes the "out of macro ID's"
problem.
There is nothing particularly tricky about the code, other than the
very performance sensitive SourceManager::getFileID() method.
