Jakob Stoklund Olesen 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.

Benjamin Kramer b328d72d77 Turns out __cxa_demangle returns the size of the buffer instead of the size of 
the demangled name. Fall back to strlen.

Jim Ingham 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.

Ted Kremenek 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
for all other C++ constructs not currently handled by the analyzer.

Douglas Gregor db48cf3c31 Don't allow vector conversions to sneak in under the guise of 
floating-point conversions or floating-integral conversions. We
really, really, really need to make isFloatingType() and friends not

Jakob Stoklund Olesen 9c47dac677 Remove the SimpleJoin optimization from SimpleRegisterCoalescing. 
Measurements show that it does not speed up coalescing, so there is no reason
the keep the added complexity around.

Benjamin Kramer 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.

Argyrios Kyrtzidis 75000b6814 Fix PR7180. 
For

void f( a:🅱️:c );

we would cache the tokens "a:🅱️:" but then we would try to annotate them using the range "a::".
Before annotating them with the (invalid) C++ scope spec, set it to the range of "a:🅱️:".

Argyrios Kyrtzidis cb6f346873 Make it easier to read/write the template part of FunctionDecl. 
Introduce:
-FunctionDecl::getTemplatedKind() which returns an enum signifying what kind of templated
  FunctionDecl it is.
-An overload of FunctionDecl::setFunctionTemplateSpecialization() which accepts arrays of
  TemplateArguments and TemplateArgumentLocs
-A constructor to TemplateArgumentList which accepts an array of TemplateArguments.
