a3208f9e7c Vector types are not arithmetic types, either. Note that we now ban 
__real myvec and __imag myvec, since they aren't all that useful (it's
just an identity function) but we might want to use them in more
restricted cases in the future (e.g., "__real mycomplexvec" could
extract the real parts of a vector of complex numbers).

c646d13054 Teach Type::isRealType() that vector types are never real types. All 
of the callers of isRealType() already assumed this, and one of them
(increment/decrement) mistakenly permitted increments of vector types
because of it.

49b4d73451 Type Type::isRealFloatingType() that vectors are not floating-point 
types, updating callers of both isFloatingType() and
isRealFloatingType() accordingly. Caught at least one issue where we
allowed one to declare a vector of vectors (!), along with cleaning up
the standard-conversion logic for C++.

87f75f75be If a metadata operand is seeded in value map and the metadata should also be seeded in value map. This is not limited to function local metadata. 
Failure to seed metdata in such cases causes troubles when in a cloned module, metadata from a new module refers to values in old module. Usually this results in mysterious bugpoint crashes. For example,

4ffbad1904 Change Type::isFloatingType() to reflect the actual definition of a 
"floating type" in C, which does not include vector types. Introduce
Type::hasFloatingRepresentation() for the places where we want to know
whether the underlying representation is one or more floating-point
values. Remove some hacks we had where the former behavior of
Type::isFloatingType() was at odds with the language definition of the
term.

1023f6bd98 Also convert SUBREG_TO_REG to a KILL when relevant, like the other subreg 
instructions.

This does not affect codegen much because SUBREG_TO_REG is only used by X86 and
X86 does not use the register scavenger, but it prevents verifier errors.

05407f6b25 Make an explicit GetThreadSpecNoCreate accessor so you don't have to get the const-ness right to ensure you are not making a copy of the owning breakpoint's ThreadSpec in a breakpoint location. Also change the name from NoCopy to NoCreate since that's clearer.

55081f9317 Don't assert on C++ casts that are currently not handled by the static analyzer. 
Instead, halt the analysis of the current path, which is what we do in GRExprEngine::ProcessStmt

53a61dc531 Ensure GetDemangledName's thread safety by making the demangle buffer thread specific. 
I'm not sure when multiple threads enter this method but a race-condition
causing a crash in malloc can be reproduced with this little script:

echo file $(which lldb) > cmd
echo "run\nbreak set -n main\nrun\nexit" >> cmd
lldb -s cmd

It may need a few runs before it crashes though.
