Fangrui Song 9e33c09647 [ELF] Keep orphan section names (.rodata.foo .text.foo) unchanged if !hasSectionsCommand
This behavior matches GNU ld and seems reasonable.

```
// If a SECTIONS command is not specified
.text.* -> .text
.rodata.* -> .rodata
.init_array.* -> .init_array
```

A proposed Linux feature CONFIG_FG_KASLR may depend on the GNU ld behavior.

Reword a comment about -z keep-text-section-prefix and a comment about
CommonSection (deleted by rL286234).
