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.

function that returns a CFxxxRef, not just functions whose name begins with
CF.  This implements <rdar://problem/5917879>.

Added test case for this feature.

Updated calls to CStrInCStrNoCase to swap their arguments, per compatibility
with strcasestr.

by an instance of LibCallInfo to provide mod/ref info of
standard library functions.  This is powerful enough to
say that 'sqrt' is readonly except that it modifies errno,
or that "printf doesn't store to memory unless the %n
constraint is present" etc.

on x86-64 linux.  This causes no regressions on
32 bit linux and 32 bit ppc.  More tests pass
on 64 bit ppc with no regressions.  I didn't
turn on eh on 64 bit linux because the intrinsics
needed to compile the eh runtime aren't done
yet.  But if you turn it on and link with the
mainline runtime then eh seems to work fine
on x86-64 linux with this patch.  Thanks to
Dale for testing.  The main point of the patch
is that if you output that some object is
encoded using 4 bytes you had better not output
8 bytes for it: the patch makes everything
consistent.
