  Log Message:
  -----------
  [MCDwarf] Respect -fdebug-prefix-map= for generated assembly debug info (DWARF v5)

For generated assembly debug info, MCDwarfLineTableHeader::CompilationDir is an
unmapped path set in MCContext::setGenDwarfRootFile. Remap it.

A relative destination path of -fdebug-prefix-map= exposes a llvm-dwarfdump bug
which joins relative DW_AT_comp_dir and directories[0].

  Log Message:
  -----------
  [DebugInfo] Don't join DW_AT_comp_dir and directories[0] for DWARF v5 line tables

DWARF v5 6.2.4 The Line Number Program Header says:

> The first entry is the current directory of the compilation. Each additional
> path entry is either a full path name or is relative to the current directory of
> the compilation.

When forming a path, relative DW_AT_comp_dir and directories[0] are not supposed
to be joined together. Fix getFileNameByIndex to special case DWARF v5 DirIdx == 0.

  [DebugInfo] -fdebug-prefix-map: handle '#line "file"' for asm source

`getContext().setMCLineTableRootFile` (from D62074) sets `RootFile.Name` to
`FirstCppHashFilename`. `RootFile.Name` is not processed by -fdebug-prefix-map
and will go to DW_TAG_compile_unit's DT_AT_name and DW_TAG_label's
DW_AT_decl_file. Remap `RootFile.Name`.

  [RISCV] isImpliedByDomCondition returns an Optional<bool> not a bool.

We were incorrectly checking that it returned an implicaton result,
not that the implication result itself was true.
