Upstream support for NSConstantArray, NSConstantIntegerNumber,
NSConstant{Float,Double}Number and NSConstantDictionary.
We would've upstreamed this earlier but testing it requires
-fno-constant-nsnumber-literals, -fno-constant-nsarray-literals and
-fno-constant-nsdictionary-literals which haven't been upstreamed yet.
As a temporary workaround use the system compiler (xcrun clang) for the
constant variant of the tests.
I'm just upstreaming this. The patch and the tests were all authored by
Fred Riss.
