it has any non-trivial class-object initializers.

last patch.

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.

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.

llvm-svn: 128059

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

llvm-svn: 128057

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

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.

i486--netbsdelf.

Drop program paths on NetBSD (unused). Only include lib dir, if
-nostdlib is absent. Use = to allow --sysroot to work.

Downgrade err_mismatched_exception_spec to a ExtWarning in Microsoft mode. MSVC doesn't do any validation on exception specifications.

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.

 - 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.
