failing testcase
The attached gcc testcase fails:
$ llvm-g++ -o initp1 initp1.C
$ ./initp1
Aborted
That's because the constructors are being output in the wrong
order in the ctors section. EmitXXStructorList in ELFWriter.cpp
should output the ctors in decreasing numerical order of priority.
Right now it doesn't order them at all.
Interestingly, another solution is to not output the ctors
section at all! This only works for ctors/dtors generated
by gcc: it seems they use magic names that are recognized
by collect2. So it would be enough for llvm-gcc to not add
ctors to llvm.global_ctors at all, and just mark them as used.
