Rather than allocating Decl objects with an Allocator, we instead allocate
them with a SegmentedList. This provides four advantages:
* Stable memory so that one thread can access a Decl object while another
thread allocates additional Decl objects from this list.
* It allows us to use u32 indexes to reference Decl objects rather than
pointers, saving memory in Type, Value, and dependency sets.
* Using integers to reference Decl objects rather than pointers makes
serialization trivial.
* It provides a unique integer to be used for anonymous symbol names,
avoiding multi-threaded contention on an atomic counter.

This gives us insight as to what is happening when we are waiting for
things such as LLVM emit object and LLD linking.

allow test cases to chose wether to link libc or not.
default behavior is to not link libc, except for `exeUsingLLVMBackend`

sample command:
/home/guw/github/zig/stage2/bin/zig build-obj cuda_kernel.zig -target nvptx64-cuda -O ReleaseSafe
this will create a kernel.ptx
expose PtxKernel call convention from LLVM
kernels are `export fn f() callconv(.PtxKernel)`
