Changes in directory llvm/lib/System/Linux:
Path.cpp updated: 1.1 -> 1.2
---
Log message:
Revise the design of the Path concept per peer review. Too many changes to
note individually but these essence of it is to not derive from
std::string, clarify the interface, and provide better documentation.
There is now also (untested) implementations for AIX, Darwin, and SunOS.

Diffs of the changes: (+20 -2)
