Subject: Parse sections containing Objective-C constants

This adds support for the `__objc_arrayobj`, `_objc_dictobj`,
`__objc_intobj`, `__objc_floatobj`, `__objc_doubleobj` and
`__objc_dateobj` sections that contain Objective-C constants. These are
emitted by Apple's versions of Clang for `const` literals, amongst other
things.
