Benjamin Kramer a3d8ced7f0 Rework InitPreprocessor to use a MacroBuilder class instead of pushing around 
std::vectors.

- MacroBuilder wraps a raw_ostream so it can easily write to any buffer
  supported by raw_ostream.
- MacroBuilder's method take Twines for easy string concatenation (this was done
  with sprintf and temporary buffers before).
- Targets still use std::vector as they don't have access to the builder.

Douglas Gregor 057e567f1b Extend -remap-file=from;to to permit mapping from a non-existent 
file. This is accomplished by introducing the notion of a "virtual"
file into the file manager, which provides a FileEntry* for a named
file whose size and modification time are known but which may not
exist on disk.

Added a cute little test that remaps both a .c file and a .h file it
includes to alternative files.

Eli Friedman bf22be630e PR4247: Widen the buffer slightly so it can hold all the definitions for 
PPC double double.

(No testcase because no normal target uses the format at the moment.)

Fariborz Jahanian 34e65770ad This patch adds support for sender-aware dispatch in Objective-C for the GNU runtime, when 
compiled with -fobjc-sender-dependent-dispatch.  This is used in AOP, COP, implementing object 
planes, and a few other things.
Patch by David Chisnall.

Chris Lattner dcdecf4a77 Fix processing of -Ufoo to not inject "#undef foo 1" into the predefines 
buffer.  This caused exciting nonsense like this:

$ clang t.c -fsyntax-only -UMACRO
In file included from <built-in>:104:
<command line>:1:14: warning: extra tokens at end of #undef directive [-Wextra-tokens]
#undef MACRO 1

Daniel Dunbar 1e7c6b6787 Add another workaround for -include. 
- If we don't find a file looking relative to the current working
   directory, fall back to header search. This is closer to what would
   happen if the lookup was starting from right directory in the first
   place (except it will find files in the directory of the main
   source file, which I *think* should not be found).

 - PR3992.

Chris Lattner 3936024941 Fix rdar://6814950 - stdint.h isn't "-pedantic -std=c89" clean, 
by marking the predefines buffer as a system header.  The problem 
with stdint is that it was getting problems like this:

/Volumes/Projects/cvs/llvm/Debug/lib/clang/1.0/include/stdint.h:43:9: warning: 'long long' is an extension when C99 mode is not enabled
typedef __INT64_TYPE__ int64_t;
        ^
<built-in>:73:29: note: instantiated from:
#define __INT64_TYPE__ long long
                            ^

We correctly silence warnings in system headers, but only if the 
spelling location of the token came from the system header.  This is
designed so that if you use a system macro in your code that you don't
get punished for its definition.  This is all cool except that the 
predefines buffer wasn't considered a system header.
