Perform wildcard expansion in Process::GetArgumentVector on Windows (PR17098)
On Windows, wildcard expansion isn't performed by the shell, but left to the
program itself. The common way to do this is to link with setargv.obj, which
performs the expansion on argc/argv before main is entered. However, we don't
use argv in Clang on Windows, but instead call GetCommandLineW so we can handle
unicode arguments. This means we have to do wildcard expansion ourselves.
A test case will be added on the Clang side.

Fixed the an objective C test case so it passes correctly.
Fixed the test case to use a runtime function prototype that will be correct ([NSString stringWithCString: "new"]) instead of one that won't (expression str = [NSString stringWithFormat: @"%cew", 'N']). The runtime doesn't track vararg functions correctly so we can't reconstitute the function correctly.
Also fixed some expressions that used "str_id" whose type was "id" and do the necessary casting since "id" doesn't have any methods.

Any commands that are executed through the public interface using SBCommandInterpreter::HandleCommand() are assumed to be in non-interactive mode.
Any commands that want interactivity (stdin) will need to be executed through the normal command interpreter using the debugger's in/out/err file handles, or by using "command source".
Individual commands through the API will have their STDIN disabled. The STDOUT and STDERR will be redirected into the SBCommandReturnObject argument to SBCommandInterpreter::HandleCommand() as usual.
This helps with a deadlock situation in an IDE (Xcode) where the IDE was managing the breakpoint actions by setting a breakpoint callback and doing things manually.

[DAGCombiner] Avoid calling method 'isShuffleMaskLegal' on illegal vector types.
This patch fixes a crasher in method 'DAGCombiner::visitOR' due to an invalid
call to method 'isShuffleMaskLegal'. On x86, method 'isShuffleMaskLegal'
always expects a legal vector value type in input.
With this patch, we immediately check if the input OR dag node has a legal
vector type; we only try to fold a OR dag node into a single shufflevector
if we know that the resulting shuffle will have a legal type.
This is to avoid calling method 'isShuffleMaskLegal' on a potentially
illegal vector value type.
Added a new test-case to file 'CodeGen/X86/combine-or.ll' to verify that
DAGCombiner doesn't crash in the attempt to check/combine an OR between shuffles
with illegal types.
