This removes the final dependency edge from any lib outside of CodeGen
to core.  As a result we can, and do, trim the dependency on core
from libclang, PrintFunctionNames, the unit tests and c-index-test.
While at it, review and trim other unneeded dependencies.

enumeration type, we were generating an integer literal implicitly
casted to the appropriate enumeration type. However, later checks on
that expression would strip the implicit cast.

This commit tweaks the lame hack, by creating an explicit cast instead
of an implicit cast. The right answer is to introduce a 
SubstNonTypeTemplateParmExpr expression that acts like the substituted
result. I'll investigate that soon.

Eliminate the internal command-line option for viewing inheritance in C++ classes, since it's only really worked for the trivial cases anyway due to lame pseudo-parsing of the class name. The viewInheritance() function is still available for use in the debugger, where this is far more useful

class and to bind the shared value using OpaqueValueExpr.  This fixes an
unnoticed problem with deserialization of these expressions where the
deserialized form would lose the vital pointer-equality trait;  or rather,
it fixes it because this patch also does the right thing for deserializing
OVEs.

Change OVEs to not be a "temporary object" in the sense that copy elision is
permitted.

This new representation is not totally unawkward to work with, but I think
that's really part and parcel with the semantics we're modelling here.  In
particular, it's much easier to fix things like the copy elision bug and to
make the CFG look right.

I've tried to update the analyzer to deal with this in at least some          
obvious cases, and I think we get a much better CFG out, but the printing
of OpaqueValueExprs probably needs some work.
