Benjamin Kramer ce276e3822 Don't clear OverloadCandidateSets on destruction, it has no effect anymore. 
And clearing a SmallPtrSet can be an expensive operation.

John McCall 6a4fa52b37 The emission of an Objective-C++'s class .cxx_destruct method should be 
conditioned on whether it has any destructible ivars, not on whether
it has any non-trivial class-object initializers.

John McCall 8f9a42971e Fix a test case and teach ClearLinkageCache() to clear the linkage of 
a function template decl's pattern, which was suddenly exposed by my
last patch.

John McCall 290b32b90f File-scope static functions need to be mangled with 'L' so that 
they don't collide with file-scope extern functions from the same
translation unit.  This is basically a matter of applying the same
logic to FunctionDecls as we were previously applying to VarDecls.

Ted Kremenek 022a4904fa Rework crash recovery cleanup in ASTUnit and CIndex to recover more memory during a Sema crash (we have just a handful of leaks left) 
and to use the simplified cleanup registration API.

Ted Kremenek 288fb9dc6e Remove crash recovery cleanups from TypeLocBuilder. They were a bit error prone, only hit in rare cases.

Ted Kremenek 4c9d46b310 Migrate 'PrettySTackTraceParserEntry' object out of Parser, and have it constructed within ParseAST. This avoids double crashes 
during crash recovery.

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.
