If a symbol is defined in an archive, when we replace its body
the isUsedInRegularObj wasn't set correctly. Internalize makes
its decision based on that bit so we ended up internalizing

This should fix. Thanks to Peter and Rafael for discussion

[Objective-C] Introduce objc_runtime_visible attribute.
The objc_runtime_visible attribute deals with an odd corner case where
a particular Objective-C class is known to the Objective-C runtime
(and, therefore, accessible by name) but its symbol has been hidden
for some reason. For such classes, teach CodeGen to use
objc_lookUpClass to retrieve the Class object, rather than referencing
the class symbol directly.
Classes annotated with objc_runtime_visible have two major limitations
that fall out from places where Objective-C metadata needs to refer to
the class (or metaclass) symbol directly:
* One cannot implement a subclass of an objc_runtime_visible class.
* One cannot implement a category on an objc_runtime_visible class.

Fixed an issue where if we have DWARF in an executable that has multiple languages where these languages use different type systems, you can end up trying to find the actualy definition for a forward declaration for a type, you will call:
TypeSP SymbolFileDWARF::FindDefinitionTypeForDWARFDeclContext (const DWARFDeclContext &dwarf_decl_ctx);
The problem was we might be looking for a type "Foo", and find one from another langauge. Then the DWARFASTParserClang would try to make an AST type using a CompilerType that might return an empty.
This fix makes sure that when we create a DWARFDeclContext from a DWARFDIE that the DWARFDeclContext we set the language of the DIE. Then when we go to find matches for DWARFDeclContext, we end up with bunch of DIEs. We check each DWARFDIE that we found by asking it for its language and making sure the language is compatible with the type system that we want to use. This keeps us from using the wrong types to resolve forward declarations.

ThinLTO: special handling for LinkOnce functions
These function can be dropped by the compiler if they are no longer
referenced in the current module. However there is a change that
another module is still referencing them because of the import.
Multiple solutions can be used:
- Always import LinkOnce when a caller is imported. This ensure that
every module with a call to a LinkOnce has the definition and will
be able to emit it if it emits the call.
- Turn the LinkOnce into Weak, so that it is always emitted.
- Turn all LinkOnce into available_externally and come back after all
modules are codegen'ed to emit only one copy of the linkonce, when
there is still a reference to it.
This patch implement the second option, with am optimization that
only *one* module will turn the LinkOnce into Weak, while the others
will turn it into available_externally, so that there is exactly one
copy emitted for the whole compilation.

Fix for pr24346: arm asm label calculation error in sub
Some ARM instructions encode 32-bit immediates as a 8-bit integer (0-255)
and a 4-bit rotation (0-30, even) in its least significant 12 bits. The
original fixup, FK_Data_4, patches the instruction by the value bit-to-bit,
regardless of the encoding. For example, assuming the label L1 and L2 are
0x0 and 0x104 respectively, the following instruction:
add r0, r0, #(L2 - L1) ; expects 0x104, i.e., 260
would be assembled to the following, which adds 1 to r0, instead of 260:
e2800104 add r0, r0, #4, 2 ; equivalently 1
The new fixup kind fixup_arm_mod_imm takes care of the encoding:
e2800f41 add r0, r0, #260
