This relands the commit previously reverted in
`8570bee53a8ce0c5d04bc11f288e19a457474c4c` due to failures on linux.
The problem was that the test executable was built with absolute
OSO prefix paths. This re-commit adds a modified version of the
executable that strips the absolute OSO prefix paths and makes
sure the test appends the OSO prefix appropriately (via the appropriate
dsymutil flags).

This reverts commit ccee9b7839a182fc692a65f563abf76f81dd436c.
This started failing on Linux buildbots. The executable wasn't generated
correctly.

**Summary**
After this patch, `dsymutil` will preserve `DW_TAG_imported_declarations`
entries in accelerator tables.
This allows consumers to resolve imported declarations even on
executables processsed through dsymutil.
This helps consumers, particularly LLDB's expression evaluator,
to resolve imported declarations (i.e., useful for namespace aliases
in C++) more efficiently.
**Testing**
* Added unit-test
