Fixed the build breakage, sorry for that.

vector of the same element type and half the width, with the high, low, even,
and odd elements respectively.

Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector.  This is fairly convenient syntax for some insert/extract
operations.

Remove some unnecessary methods/types in the ExtVectorElementExpr class.

also need to be checked for memory modifying instructions before we
can sink them.  THis fixes the second half of PR2297.

delete the first store in:

store x -> p
load p
store y -> p

This is for PR2297.

Darwin.  This is a hack of course, but it does
at least look at the right thing: gotpcrel means
that this is already an offset, so an explicit
offset is not needed (and wrong).  I think this
is good enough for the moment: Anton is working
on something better.

Added -g command line options to clang for generating source level debug information. This patch currently enables generation of line number debug information (stoppoints) and region begin/end debug information. The new files CGDebugInfo.h and CGDebugInfo.cpp implements the debug info manager class CGDebugInfo.
