This is a resubmit of r223548, which was reverted due to breaking
tests on Linux and Mac.
This resubmit fixes the reason for the revert by adding back some
accidentally removed code which appends -c to the command line
when running /bin/sh.
This resubmit also differs from the original patch in that it sets
the architecture on the ProcessLaunchInfo. A follow-up patch will
refactor this to separate the logic for different platforms.

More specifically, this change can be summarized as follows:
1) Makes an lldbHostPosix library which contains code common to
all posix platforms.
2) Creates Host/FileSystem.h which defines a common FileSystem
interface.
3) Implements FileSystem.h in Host/windows and Host/posix.
4) Creates Host/FileCache.h, implemented in Host/common, which
defines a class useful for storing handles to open files needed
by the debugger.
