bae0e68930 Fix PR3988: extern inline functions get strong symbol definitions in 
C99 mode.  This is a regression from an earlier patch of mine.

This also simplifies the linkage enums a bit.

02e987f3e8 implement codegen support for __attribute((__gnuc_inline__)), 
pulling some attribute munging stuff into GetLinkageForFunction.

This should fix PR3986

389325715b Refactor how attributes are set on values. 
- Pull out SetCommonAttributes, which handles the things common to
   aliases, methods, functions, and variables.

 - Pull out SetLLVMFunctionAttributesForDefinition, which handles the
   LLVM attributes which we only want to apply to a definition (like
   noinline and alwaysinline).

 - Kill SetGVDeclarationAttributes (inlined into SetFunctionAttributes
   and specialized).

 - Kill SetFunctionAttributesForDefinition (inlined into sole caller).

 - Inline SetGVDefinitionAttributes into SetMethodAttributes and
   specialize.

 - Rename SetGVDefinitionAttributes to SetFunctionDefinitionAttributes.

This is supposed to be a no functionality change commit, but I may
have made a mistake.

169a5c963f give always_inline functions internal linkage. If they cannot be 
inlined for some reason, then we don't want a strong or even weak
definition.

15894b791b Various fixes to symbols used for Obj-C x86_64 metadata. 
- Changed method names to match gcc (categories names still aren't
   mangled in).

 - Expose correct name for class and metadata symbols (although
   -fvisibility=hidden isn't yet correct).

 - Remove several things from llvm.used that didn't need to be there
   (I suspect this can still be trimmed).

 - Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not
   needed).

 - Hide EH type class info with -fvisibility=hidden

 - Change setGlobal[Option]Visibility to not change the visibility of
   functions with internal linkage.

8d816d6cb5 CodeGenModule::GetAddrOfConstantCFString(): 
- Finish up support for converting UTF8->UTF16 to support ObjC @"string" constants.

Remove warning from CheckObjCString.

As the FIXME in the test case indicates, I still have a bug to work out (apparently with \u handling).

29cae66bde Add ConvertUTF module from http://www.unicode.org/Public/PROGRAMS/CVTUTF. 
#ifdef'd out the 5 conversion routines that we don't currently need.

Still need a bit more work in GetAddrOfConstantCFString(). Added a FIXME to indicate this.

Expect to remove the FIXME today...

08b216abf1 Add Target hooks for IRgen of [cf]string literals. 
- Notably, set section on cfstring literal string data (for now, this
   is done everywhere because it matches what we were already doing
   for the CFString data itself)
