[MC] Fix DWARF file table for files with empty DWARF (#119572)
Update root file in DWARF file/line table as soon as we see the first
"#line" directive.
This was moved from "enabledGenDwarfForAssembly", which is called right
before we emit DWARF information. But if the file is empty or contains
expressions that doesn't need DWARF, it is never called, leaving an
original root file and not the file in the "#line" directive.
Add a test checking for this case.
This is reapply of #119229 with the following fix:
"MCContext::setMCLineTableRootFile" has the effect of adding
".debug_line" section to the output, even if DWARF generation is
disabled. Add a check and a test for this case.
Fixes: #119020
Fixes: #119229
