Change inline-breakpoint-strategy setting to default to eInlineBreakpointsAlways strategy.

See thread started here for motivation:
http://lists.cs.uiuc.edu/pipermail/lldb-dev/2014-September/005225.html

This change enables the ability to set breakpoints in ccache-based and executables that
make use of preprocessed source files.  This ability existed in lldb before, but was off
by default.

Change by Doug Snyder.
