Bill Wendling 73e465e148 Have 'addFnAttr' take the attribute enum value. Then have it build the attribute object and add it appropriately. No functionality change.

Bill Wendling 0597c1e53c We use the enums to query whether an Attributes object has that attribute. The 
opaque layer is responsible for knowing where that specific attribute is stored.

Richard Smith b555a767ba PR13941: Mark all virtual functions as unnamed_addr. It's not possible to 
observe their addresses (taking their address gives the vtable slot) so we are
free to merge their definitions.

Eric Christopher f8378ca2b1 Remove HasSynthBitfield and all callers/writers/etc. Also remove 
previous ResetObjCLayout calls since this is now handled in Sema.

Hans Wennborg f60f6af9e8 Add -ftls-model command-line flag. 
This allows for setting the default TLS model. (PR9788)

Fariborz Jahanian 6362803cfe block literal irgen: several improvements on naming block 
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).

Hans Wennborg d3b01bc7c6 Support the tls_model attribute (PR9788) 
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.

John McCall 5fb5df9c83 Restructure how the driver communicates information about the 
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.

Richard Smith 2b013185f8 PR13064: Store whether an in-class initializer uses direct or copy

David Blaikie 40ed29730b Revert Decl's iterators back to pointer value_type rather than reference value_type 
In addition, I've made the pointer and reference typedef 'void' rather than T*
just so they can't get misused. I would've omitted them entirely but
std::distance likes them to be there even if it doesn't use them.

This rolls back r155808 and r155869.

Review by Doug Gregor incorporating feedback from Chandler Carruth.
