[PATCH] D48988: Debug prefix map for machine code emission

[Siddhartha Bagaria via Phabricator via llvm-commits]

Simplify code.

- Remap DWARF dirs in place before calling Emit.
- Remap compilation dir in place before calling Emit.

In-place editing ensures we did not miss a place, and simplifies lifecycle
management of the strings.

The option is available only through llvm-mc and cc1as.

All regression tests pass.
