Use runtime bitcode to get size of primitive types

Browse Source 
As an alternative to explicitly setting type size in konan.properties or
backend code we can "ask" LLVM about it.
Unfortunately, there is no Clang/LLVM API for it,
so we use a trivial workaround:
Create dumb function in runtime code, and then extract info about
return type size using LLVM.
