Codegen support for fastcall & stdcall CC.
Patch by Ilya Okonsky!

llvm-svn: 59080

LinkageSpecDecl is c++ specific, move it to DeclCXX

llvm-svn: 58704

Don't run the verifier as part of IRgen, this is now down (per module)
in the driver (this means we no longer run the verifier per function, however).

llvm-svn: 58307

Add attribute always_inline support.

llvm-svn: 58304

Add option argument to GetAddrOfConstantString to use for name of
(first) global holding the string.
- No functionality change.

llvm-svn: 57736

Change CGDebugInfo::setLocation to just ignore invalid locations. This
simplifies clients.

Also, add assert that RegionStack is empty when the CGDebugInfo is
destroyed.

Add simple interface for protecting runtime functions from name
collisions.
- Provide CodeGenModule::CreateRuntimeFunction which guarantees that
the function it creates will have the provided name in the final
module. This allows the runtime to have its functions protected
from declarations of the same name in the source code.

- One could argue that this is a reason to abuse the llvm::Module
namespace for dealing with function redeclarations. However, that
approach seems conceptually flawed to me. This one also happens to
be somewhat more efficient.

No functionality change.

Now Attributes are divided in three groups
- return attributes - inreg, zext and sext
- parameter attributes
- function attributes - nounwind, readonly, readnone, noreturn

Return attributes use 0 as the index.
Function attributes use ~0U as the index.

This sets the stage
- to implement function notes as function attributes and

Move FunctionType conversion into CGCall.cpp:
- Added CodeGenTypes::GetFunctionType, taking a CGFunctionInfo.
- Updated Obj-C runtimes to use this instead of rolling the
llvm::FunctionType by hand.
- Killed CodeGenTypes::{ConvertReturnType, DecodeArgumentTypes}.

Add ABIArgInfo class to encapsulate ABI decision of how to lower types
to LLVM.
- Will move to target sometime soon.

Fix a number of issues w.r.t. emission of global for functions and
aliases.
- Attributes specific to a definition are only set when the
definition is seen.
- Alias generation is delayed until the end of the module; necessary
since the alias may reference forward.
- Fixes: PR2743, <rdr://6140807&6094512>
- Improves: <rdr://6095112> (added XFAIL)

Also, print module on verification failures.

epilog code.

Change WarnUnsupported to ErrorUnsupported (in name and in practice).
- We are beyond the point where this shows up often and when it does
generating miscompiled files is bad.
