9fd460821f elf: cleanup phdr tracking 
Since one of the program header entries is now the program header table
itself, we can avoid tracking it explicitly and just track it as yet
another program segment.

f4b411314c Sema: defer stores to inferred allocs 
This lets us generate the store with knowledge of the type to be stored.
Therefore, we can avoid generating garbage Air with stores through
pointers to comptime-only types which backends cannot lower.

a88c0b4d08 link: handle -u flag in all linkers 
Also clean up parsing of linker args - reuse `ArgsIterator`.

In MachO, ensure we add every symbol marked with `-u` as undefined
before proceeding with symbol resolution. Additionally, ensure those
symbols are never garbage collected.

MachO entry_in_dylib test: pass `-u _my_main` when linking executable
so that it is not incorrectly garbage collected by the linker.

ee0c445765 coff: due to ASLR we need to dupe the code for relocating 
In addition, we need to be careful not to mark the relocations as
resolved prematurely as then we are risking malforming the binary
as we need to resolve the relocs twice: once for in-memory writes,
and once for in-file updates.

22e1b03360 coff: use copy in zig-cache for child process in HCS 
Ideally, we would just do an atomic rename, but so far I had no
luck. I have also tried marking the file to delete-on-close but
then we cannot use it to spawn the process. So for now, let's just
put a copy in `zig-cache` and let the user decide when to recycle
the cache dir.

3357c59ceb new builtins: @workItemId, @workGroupId, @workGroupSize 
* @workItemId returns the index of the work item in a work group for a
  dimension.
* @workGroupId returns the index of the work group in the kernel dispatch for a
  dimension.
* @workGroupSize returns the size of the work group for a dimension.

These builtins are mainly useful for GPU backends. They are currently only
implemented for the AMDGCN LLVM backend.

11903436a9 llvm/bpf: disable llvm builtins for bpf target 
As bpf program has no global section for constant values (especially strings),
so use llvm's builtins (like memcpy, memset, etc) will lead to compilation failure
(something like this: A call to built-in function 'memcpy' is not supported.)

0543def52f llvm: fix crashes when loading a struct field 
The result of buildStructGEP is not always a GEP (sorry), so we can't
use getGEPResultElementType on it.

dd66e0addb Sema: fix empty slice pointer value 
We just checked that inst_child_ty was effectively a zero-bit type, so
it is certainly not the non-zero alignment we are looking for.
