when preprocessing a .S file, unknown directives should just be passed through,
and the token after the # should be expanded if it is not a valid directive.
This allows us to transform things like:

#define FOO BAR
# FOO

into # BAR, even though FOO is not normally expanded for directives.

This should fix PR3833

Driver: Add "d" flag to Options.def for options which are completely

 - This is not very precise, we use it to drive the "forward-to-gcc"
   predicate, when trying to talk to a generic gcc tool.

 - Slightly better than what ccc was doing, and should be good
   enough. Platforms which want a robust driver should implement a
   proper tool chain.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67172 91177308-0d34-0410-b5e6-96231b3b80d8

Stub out some code for support for NSDeallocateObject. This is enabled yet until
we resolve the semantics of this function when GC is enabled.

GCC 4.0 isn't happy with VISIBILITY_HIDDEN on a namespace.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67112 91177308-0d34-0410-b5e6-96231b3b80d8

Driver: Stub out generic GCC tool selection (missed a file)

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67109 91177308-0d34-0410-b5e6-96231b3b80d8

Driver: Stub out generic GCC tool selection.

Driver: Stub out generic GCC tool chain implementation.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67107 91177308-0d34-0410-b5e6-96231b3b80d8

Driver: Make sure to get the default arch name from the tool chain, not the
host; the toolchain may differ based on command line arguments.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67106 91177308-0d34-0410-b5e6-96231b3b80d8

Driver: Pass HostInfo reference into ToolChain.

Refactor instantiation of declarations within a template into a much
cleaner visitor framework.

Added a visitor for declarations, which is quite similar to the
visitor for statatements.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67104 91177308-0d34-0410-b5e6-96231b3b80d8

Driver: Pass Driver reference down into Host info, which will need it
to pass to ToolChains, which may need Driver specific information (for
example, to form search paths).

retain/release checker: Add support for reasoning about -dealloc.

Implement instantiation of enums within class templates. This isn't
quite as great as it sounds, because, while we can refer to the
enumerator values outside the template, e.g.,

  adder<long, 3, 4>::value

we can't yet refer to them with dependent names, so no Fibonacci
(yet).

InstantiateClassTemplateSpecialization is getting messy; next commit
will put it into a less-ugly state.

Driver: Hide HostInfo implementations.
 - Also, normalize arch names a tad and stub out getToolChain
   implementations.

Driver: Add two option form of ArgList::getLastArg.

Driver: Add logic for computing where to put job outputs (pipe,
temporary file, user provided name, derived name).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67088 91177308-0d34-0410-b5e6-96231b3b80d8

Driver: Add list of temporary and result files to Compilation.

Add ArgList::MakeArgString and make ArgList::Make* const.
 - Slightly strange, but the idea is that the ArgList data structure
   is primarily a list of arguments; we want to allow clients to still
   add argument strings to an ArgList to avoid worrying about string
   lifetimes (or unnecessary string copying).
