* Convert draft to generate all relevant segments and sections in right places
* Do not prealloc space in text blocks until we can NOP
* Write out LC_LOAD_DYLINKER command
* Add LC_LOAD_DYLIB command in order to specify to load libSystem
* Redo update decl exports (similar to Elf globals, globals need to be contiguous in
memory)
Fixes a bug where the last written load command would accidentally
override the beginning of the __text section. Also defines missing
MachO constants and relocation structs/enums.

The `entry_point_command` is a replacement for `thread_command`, and
is used for main executables to specify the location of `main()`
entry point.

This commit write out Mach-O header in the linker's `flush`
method. The header currently only populates the magic number,
filetype, and cpu info.
