Measurements show that it does not speed up coalescing, so there is no reason
the keep the added complexity around.

Also clean out some unused methods and static functions.

This also moves strlen out of the mutex scope.

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.

require a proper preheader.

When we ask for the enumerators of an EnumDecl, make sure we get them even if we have a EnumDecl that is not the definition of the enumeration

For

void f( a::b::c );

we would cache the tokens "a::b::" 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::b::".

-Introduce PCHWriter::AddTemplateArgumentLocInfo()
-Modify PCHWriter::AddTemplateArgumentLoc() to also write TemplateArgumentLoc's TemplateArgument
  and move the existing calls of AddTemplateArgumentLoc() to AddTemplateArgumentLocInfo().

llvm-svn: 106533

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.

if/while/switch/for statements to ensure that walking the children of
these statements actually works. Previously, we stored the condition
variable as a VarDecl. However, StmtIterator isn't able to walk from a
VarDecl to a set of statements, and would (in some circumstances) walk
beyond the end of the list of statements, cause Bad Behavior.

In this change, we've gone back to representing the condition
variables as DeclStmts. While not as memory-efficient as VarDecls, it
greatly simplifies iteration over the children. 

Fixes the remainder of <rdar://problem/8104754>.
