Daniel Dunbar fe908a805b Frontend: Change CC_PRINT_HEADERS to not print header depth markers, these don't 
really make any sense in this environment.

Ted Kremenek 5e14d39a88 Improve crash recovery cleanup to recovery CompilerInstances during crash recovery. This was a huge resource "root" during crashes. 
This change requires making a bunch of fundamental Clang structures (optionally) reference counted to allow correct
ownership semantics of these objects (e.g., ASTContext) to play out between an active ASTUnit and CompilerInstance
object.

Joerg Sonnenberger fcc3ec90a5 Introduce FindTargetProgramPath to check for a target-specific helper 
program and fallback to plain version otherwise. Use this for the NetBSD
target to make it try e.g. i486--netbsdelf-as and -ld for target
i486--netbsdelf.

Joerg Sonnenberger bc923f3f7d Memorize presence/absence of -nostdlib in Driver. 
Drop program paths on NetBSD (unused). Only include lib dir, if
-nostdlib is absent. Use = to allow --sysroot to work.

Joerg Sonnenberger 6165ab1132 Remember sysroot in Driver. Pass it down to ld for NetBSD, FreeBSD 
and DragonFly. Use the --sysroot= form for Linux. Fix handling of =
prefix for -B.

Ted Kremenek ddc06d0bd0 Rename class 'CFGReachabilityAnalysis' to 'CFGReverseBlockReachabilityAnalysis'. 
This rename serves two purposes:

- It reflects the actual functionality of this analysis.
- We will have more than one reachability analysis.

Peter Collingbourne 599cb8e430 Add support for language-specific address spaces. On top of that, 
add support for the OpenCL __private, __local, __constant and
__global address spaces, as well as the __read_only, _read_write and
__write_only image access specifiers.  Patch originally by ARM;
language-specific address space support by myself.

Daniel Dunbar 8c3d735118 Driver: Forward -traditional and -traditional-cpp in preprocessing modes. 
- We don't really support the majority of the horrible -traditional-cpp
   behavior, but it is unlikely that we ever will either. This allows us to
   start trying to use clang as a /usr/bin/cpp replacement and see what pieces
   of -traditional-cpp mode people actually care about.

Daniel Dunbar 1057f86d0e Lexer: Add extremely limited support for -traditional-cpp, ignoring BCPL

John McCall 7ef5cb3038 The Darwin kernel does not provide useful guard variable support. 
Issue this as an IR-gen error;  it's not really worthwhile doing this
"right", i.e. in Sema, because IR gen knows a lot of tricks beyond
what the constant evaluator knows.
