a860e6aebc Introduce a -cc1-level option to turn off related result type 
inference, to be used (only) by the Objective-C rewriter.

c9224d6714 Eliminate the -f[no]objc-infer-related-result-type flags; there's no 
reason to allow the user to control these semantics through a flag.

33823727c8 Implement Objective-C Related Result Type semantics. 
Related result types apply Cocoa conventions to the type of message
sends and property accesses to Objective-C methods that are known to
always return objects whose type is the same as the type of the
receiving class (or a subclass thereof), such as +alloc and
-init. This tightens up static type safety for Objective-C, so that we
now diagnose mistakes like this:

t.m:4:10: warning: incompatible pointer types initializing 'NSSet *'
with an
      expression of type 'NSArray *' [-Wincompatible-pointer-types]
  NSSet *array = [[NSArray alloc] init];
         ^       ~~~~~~~~~~~~~~~~~~~~~~
/System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:72:1:
note: 
      instance method 'init' is assumed to return an instance of its
      receiver
      type ('NSArray *')
- (id)init;
^

It also means that we get decent type inference when writing code in
Objective-C++0x:

  auto array = [[NSMutableArray alloc] initWithObjects:@"one",  @"two",nil];
  //    ^ now infers NSMutableArray* rather than id

87717773e2 Sort -lgcc after -lgcc_s for NetBSD, otherwise shared libraries on i386 
may pick it up. This would create bad text relocations.

62188bbb90 Identifiers with _CapitalLetter are reserved, so don't use them. Prefer the 
common C++ pattern of using the same name for the constructor argument as you
do for the member. Noticed by inspection.

304902141e We were looking at /usr/lib only if the distro had multilib. This is bogus: 
we look in /usr/lib to find crt1.o, and that depends only on where libc
is installed.

This fixes the case of using a different gcc installation in a distro
without multilib.

0ddfbe230f We already have support for using c++ headers from a custom location. 
Before this patch we would still link with the system libstdc++. It worked
fine most of the time, but would break if the used headers were a lot newer
than the system libraries.

This patch changes the driver to use the libraries corresponding to the
headers the user selected.

This fixes, for example, using 4.5 headers in a system with gcc 4.1.

0e37afa15e A StringRef-ication of the DiagnosticIDs API and internals. 
Patch by Matthieu Monrocq with tweaks by me to avoid StringRefs in the static

prints the file, line, and column of a diagnostic. We currently

-fms-extensions.

637603a7cc Make the triple an explicit argument of FindTargetProgramPath. 
Preserve the original triple in the NetBSD toolchain when using -m32 or
-m64 and the resulting effective target is different from the triple it
started with. This allows -m32 to use the same assembler/linking in
cross-compiling mode and avoids confusion about passing down target
specific flags in that case like --32.
