Summary: This change allows yaml input to control the order of implicitly added sections (`.symtab`, `.strtab`, `.shstrtab`). The order is controlled by adding a placeholder section of the given name to the Sections field. This change is to support changes in D39582, where it is desirable to control the location of the `.dynsym` section. This reapplied version fixes: 1. use of a function call within an assert 2. failing lld test which has an unnamed section 3. incorrect section count when given an unnamed section Additionally, one more test to cover the unnamed section failure.
