Chris Lattner 8322dc809e make the token lexer allocate its temporary token buffers for
preexpanded macro arguments from the preprocessor's bump pointer.
This reduces # mallocs from 12444 to 11792.

Chris Lattner 70946da73a switch the macroinfo argument lists from being allocated off the heap
to being allocated from the same bumpptr that the MacroInfo objects 
themselves are.

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

Chris Lattner ddb7191920 Next step toward making string diagnostics correct: handle
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.

Chris Lattner ec396b5114 Fix some issues handling sub-token locations that come from macro expansions.
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.

Chris Lattner 5a2e9cb42d fix PR3579: __LINE__ expands to the presumed location of the
*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.

Chris Lattner 9dc9c206d3 track "just a little more" location information for macro instantiations.
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.

Ted Kremenek 2fd18ec43a PTH: Cache directory and negative 'stat' calls. This gives us a 1% performance improvement on Cocoa.h (fsyntax-only+PTH).

Chris Lattner 9ef847be12 Fix rdar://6562329, a static analyzer crash Ted noticed on
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.

Ted Kremenek a5c2c27ebd PTH: Cache stat information for files in the PTH file. Hook up FileManager
to use this stat information in the PTH file using a 'StatSysCallCache' object.

Performance impact (Cocoa.h, PTH):
- number of stat calls reduces from 1230 to 425
- fsyntax-only: time improves by 4.2% 

We can reduce the number of stat calls to almost zero by caching negative stat
calls and directory stat calls in the PTH file as well.

Ted Kremenek 86423a9993 PTH: Replace ad hoc 'file name' -> 'PTH data' lookup table in the PTH file with an on-disk chained hash table. This data structure is implemented using templates, and will be used to replace similar data structures. This change leads to no visibile performance impact on Cocoa.h, but now we only pay a price for the table on order with the number of files accessed and not the number in the PTH file.
