The tablegen'd code does the same thing without this egregious duplication.
In my limited testing everything seems to work, however there can be
differences if the clang and llvm builtin definitions don't match.

The generated code uncovered an invalid prototype for __builtin_mips_shilo, fix it along the way.

handy. It can be done, but we would have to build a derived-to-base cast
during codegen to compute the correct this pointer.

I will handle covariant returns next.

code with canDevirtualizeMemberFunctionCalls, but that can be done in an
independent patch.

to see if we had an underlying final class or method, but we would then
use the cast type to do the call, resulting in a direct call to the wrong
method.

literal helper functions. All helper functions (global
and locals) use block_invoke as their prefix. Local literal
helper names are prefixed by their enclosing mangled function
names. Blocks in non-local initializers (e.g. a global variable 
or a C++11 field) are prefixed by their mangled variable name. 
The descriminator number added to end of the name starts off 
with blank (for first block) and _<N> (for the N+2-th block).

This adds support for the tls_model attribute. This allows the user to
choose a TLS model that is better than what LLVM would select by
default. For example, a variable might be declared as:

  __thread int x __attribute__((tls_model("initial-exec")));

if it will not be used in a shared library that is dlopen'ed.

This depends on LLVM r159077.

Heavily based on a patch from

I'll clean up the duplicated function in CodeGen as
a follow-up, later today or tomorrow.

express library-level dependencies within Clang.

This is no more verbose really, and plays nicer with the rest of the
CMake facilities. It should also have no change in functionality.

error was asserting on anything that included Windows.h.  MS-style inline asm is
still dropped, but at least now we're not completely silent about it.

CreateEnumType doesn't participate in caching so the descriptor for the enum
gets recomputed for every reference of an element of an enum, only to get
discarded when it gets turned into an MDNode.

No functionality change except performance.

target Objective-C runtime down to the frontend:  break this
down into a single target runtime kind and version, and compute
all the relevant information from that.  This makes it
relatively painless to add support for new runtimes to the
compiler.  Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z,
available at the driver level as a better and more general
alternative to -fgnu-runtime and -fnext-runtime.  This new
concept of an Objective-C runtime also encompasses what we
were previously separating out as the "Objective-C ABI", so
fragile vs. non-fragile runtimes are now really modelled as
different kinds of runtime, paving the way for better overall
differentiation.

As a sort of special case, continue to accept the -cc1 flag
-fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak.

I won't go so far as to say "no functionality change", even
ignoring the new driver flag, but subtle changes in driver
semantics are almost certainly not intended.

option. On the driver, check if we are using libraries from gcc 4.7 or newer
and if so pass -fuse-init-array to the frontend.
The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in
.ctors, so we have to use .init_array.

Fix Sema and IRGen for atomic compound assignment so it has the right semantics when promotions are involved.
(As far as I can tell, this only affects some edge cases.)
