not the start of a logical line.  Be careful about this distinction, which 
affects when newlines are printed and when paste-avoidance happens, etc.  
This fixes PR1848, thanks to Neil for noticing this!

This would cause us to emit different code (in -E mode) for these two files:

---
#define t(x) x

t(a
3)
---
#define t(x) x
t(a
3)
---

In one case, -E would print "a\n3", in the other it printed "a3".  Now
it prints "a3" for both.

This is part of PR1848.

Omit the field name when including the super class structure template.

This allows us to access a superclasses ivars without deriving the absolute path.

GetLanguage, and InitializeLangOptions.  The goal is to break up this logic
into atomic units of functionality that can later be refactored into better
driver logic that is capable of handling a mixture of source files of
different languages.

Make sure the class methods get attached to the metaclass object.

in SerializationTest (which will soon be rewritten to use this interface).

Modified: ctor of SerializationTest: Now takes LangOptions argument.  We
          will eventually serialize this as well.

deserialized ASTs into the function CreateASTConsumer().  This function

any alternative targets at this point other than "darwin," so we now default to
Darwin targets (for now).

llvm-svn: 44572

llvm-svn: 44561

we default to "i386-apple-darwin".  This is an interim solution.

Removed processing of "linux" triples from Targets.cpp, since we don't have
any sensical Linux target support (yet).

Cleaned up error processing of targets; added better diagnostics.

llvm-svn: 44560

SerializationTest (subclass of ASTConsumer) now takes Diagnostics& in its ctor.

Removed debugging fprintfs for printing targets.
Implemented error messages when processing invalid targets.

replaces the functionality previously provided by just "-arch" (which is still
supported but has different semantics).

The new behavior is as follows:

(1) If the user does not specify -triple:

   (a) If no -arch options are specified, the target triple used is the host
   triple (in llvm/Config/config.h).
   
   (b) If one or more -arch's are specified (and no -triple), then there is
       one triple for each -arch, where the specified arch is substituted
       for the arch in the host triple.  Example:
          host triple = i686-apple-darwin9
          command: clang  -arch ppc -arch ppc64 ...
          triples used: ppc-apple-darwin9  ppc64-apple-darwin9
          
(2) The user does specify a -triple (only one allowed):

  (a) If no -arch options are specified, the triple specified by -triple
      is used.  E.g clang -triple i686-apple-darwin9
      
  (b) If one or more -arch options are specified, then the triple specified
      by -triple is used as the primary target, and the arch's specified
      by -arch are used to create secondary targets.  For example:
      
      clang -triple i686-apple-darwin9 -arch ppc -arch ppc64
      
      has the following targets:
         i686-apple-darwin9  (primary target)
         ppc-apple-darwin9
         ppc64-apple-darwin9


Other changes related to the changes to the driver:

- TargetInfoImpl now includes the triple string.

- TargetInfo::getTargetTriple returns the triple for its primary target.

- test case test/Parser/portability.c has been updated because "-arch linux" is
  no longer valid ("linux" is an OS, not an arch); instead we use a bogus
  architecture "bogusW16W16" where WCharWidth=16 and WCharAlign=16.
