For the most part this was just "check isInstanceProperty"; the one feature not yet implemented
is the emission of ObjC metadata for class properties.

The -enable-omit-needless-words option attempts to omit needless words
from method names imported from Clang. Broadly speaking, a word is
needless if it merely restates the type of the corresponding parameter,
using reverse camel-case matching of the type name to the
function/parameter name. The word "With" is also considered needless
if whether follows it is needless, e.g.,
func copyWithZone(zone: NSZone)
gets reduced to
func copy(zone: NSZone)
because "Zone" merely restates type information and the remaining,
trailing "With" is also needless.
There are some special type naming rules for builtin Objective-C types,
e.g.,
id -> "Object"
SEL -> "Selector"
Block pointer types -> "Block"
as well as some very-Cocoa-specific matching rules, e.g., the type
"IndexSet" matches the name "Indexes" or "Indices".
Expect a lot of churn with these heuristics; this is part of
rdar://problem/22232287.

Also, remove calls to isSwiftReservedName in
ClangImporter::Implementation::importName(), since 'true' and 'false'
are now keywords and rdar://problem/13187570 is no longer a problem.

Also, use "#include <objc/NSObject.h>" instead of "@import ObjectiveC;"
to get access to BOOL, SEL, NSObject, and NSString.
This allows generated headers to be used in Objective-C++ contexts, where
modules don't yet work. The dependencies will unfortunately need to be
imported separately (because there's not a direct mapping from module name
back to header file), but that's still better than just being incompatible.
