rGb4b67e41443f: Eliminate p_elf_machine from struct proc.
rG5d9f790191fe: Eliminate p_elf_machine from struct proc.
Summary

Instead of p_elf_machine use machine member of the Elf_Brandinfo which is now
cached in the struct proc at p_elf_brandinfo member.

As p_elf_flags alignment is 8 bytes here is a hole, should I remove p_reserved?
