AK: Support storing blocks in AK::Function

Browse source 
This has two slightly different implementations for ARC and non-ARC
compiler modes. The main idea is to store a block pointer as our
closure and use either ARC magic or BlockRuntime methods to manage
the memory for the block. Things are complicated by the fact that
we don't yet force-enable swift, so we can't count on the swift.org
llvm fork being our compiler toolchain. The patch adds some CMake
checks and ifdefs to still support environments without support
for blocks or ARC.
