ARM: rename ARM builtins to use __builtin_arm prefix

This corrects SVN r212196's naming change to use the proper prefix of
`__builtin_arm_` instead of `__builtin_`.

Thanks to Yi Kong for pointing out the incorrect naming!

MS ABI: Get linkage of RTTI data correct

The Itanium rules are not appropriate for the MS ABI.  RTTI data is
_never_ imported and thus is never available_externally.  It is either
internal (if the type's linkage is internal) or linkonce_odr.

This also means that classes which inherit from dllimport'd bases force
their translation unit to duplicate the entirety of the RTTI data of
that base.

Interestingly, the complete object locator can never be referenced by
translation units which import the class.

This fixes PR20106.

Move the calling of emitTargetMD() later.

Summary:
Because a global created by GetOrCreateLLVMGlobal() is not finalised until later viz:
  extern char a[];
  char f(){ return a[5];}
  char a[10];

Change MangledDeclNames to use a MapVector rather than a DenseMap so that the
Metadata is output in order of original declaration, so to make deterministic
and improve human readablity.

CodeGen: add support for MSBuiltin aliases

This completes the infrastructure for the new MSBuiltin aliases in the
instruction definitions.  These behave similar to the GCCBuiltin in that they
can be implicitly constructed without special handling unless needed.

With this change it is possible to annotate an LLVM intrinsic in the backend
instruction definitions and indicate it as a builtin in the Builtin*.def files
in clang via LANGBUILTIN.  That will automatically pass through the instruction
much as a GCCBuiltin.

Note that there is no need for the special handling for ensuring that the
compatibility flag is enabled since the filtering on the LANGBUILTIN will
automatically prevent the intrinsic from bleeding into non-MS compatible
compiler invocations.
