restriction from the GCDAProfile.c"
Bill added a much more effective way of coping with the use of errno and
other system interactions for Darwin for now by disabling it on that
platform. Building against the SDK stuff is more fundamental to the
darwin build process.

Where a source tree is complete with lld, lldb and polly, it may not be possible to use cmake to configure build scripts if the host compiler it not capable of compiling these sub-projects. This change makes it possible to first build a bootstrap clang compiler when can then be used to build a complete llvm toolchain. An example bootstrap build sequence could be as follows:
$ mkdir bootstrap
$ cd bootstrap
$ cmake -G 'Unix Makefiles'
-DCMAKE_BUILD_TYPE:STRING=Release
-DCMAKE_PREFIX_PATH:STRING=$(pwd)
-DLLVM_TARGETS_TO_BUILD:STRING=host
-DLLVM_INCLUDE_TOOLS:STRING=bootstrap-only
../source
$ make clang # build clang only for host
$ cd ..
$ export CC=$(realpath bootstrap/bin)/clang
$ export CXX=$(realpath bootstrap/bin)/clang++
$ mkdir final
$ cd final
$ cmake -G 'Unix Makefiles' ../source
$ make all check-all

As noted by Richard in the post:
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130624/082605.html, the following code should not add an entry
into PendingLocalImplicitInstantiations, since local instantiations
should only occur within the context of other instantiations:
int foo(double y) {
struct Lambda {
template<class T> T operator()(T t) const { return t; };
} lambda;
return lambda(y);
}
Hence the attached code does the following:
1) In MarkFunctionReferenced, check if ActiveInstantiations.size()
is non-zero before adding to PendingLocalImplicitInstantiations.
2) In InstantiateFunctionDefinition, we swap out/in
PendingLocalImplicitInstantiations so that only those
pending local instantiations that are added during the instantiation
of the current function are instantiated recursively.

Also, print the cache hits statistics if the log is in debugging mode vs. LLDB being a debug build - this should make it easier to gather useful metrics on cache success rate for real users

The argument to -w (--category) in type * list is a regular expression
This caused unhappiness with the gnu-libstdc++ category because of the double ++
Now we check for exact textual match as-well-as regexp matching

debug statements to add a missing newline. Also canonicalize to '\n' instead of
"\n"; the latter calls a function with a loop the former does not.

(thanks!) by deferring the free of the filename until we finish writing
the coverage data to that file.
Bill, let me know if you'd prefer a different approach!

The semi-unofficial way of returning a status from a Python command was to return a string (e.g. return "no such variable was found") that LLDB would pick as a clue of an error having happened
This checkin changes that:
- SBCommandReturnObject now exports a SetError() call, which can take an SBError or a plain C-string
- script commands now drop any return value and expect the SBCommandReturnObject ("return object") to be filled in appropriately - if you do nothing, a success will be assumed
If your commands were relying on returning a value and having LLDB pick that up as an error, please change your commands to SetError() through the return object or expect changes in behavior
