[codeview] Make function names more consistent with MSVC

Names in function id records don't include nested name specifiers or
template arguments, but names in the symbol stream include both.

For the symbol stream, instead of having Clang put the fully qualified
name in the subprogram display name, recreate it from the subprogram
scope chain. For the type stream, take the unqualified name and chop of
any template arguments.

This makes it so that CodeView DI metadata is more similar to DWARF DI
metadata.

[pdb] Change type visitor pattern to be dynamic.

This allows better catching of compiler errors since we can use
the override keyword to verify that methods are actually

Also in this patch I've changed from storing a boolean Error
code everywhere to returning an llvm::Error, to propagate richer
error information up the call stack.

[DebugInfo] Add calling convention support for DWARF and CodeView

Summary:
Now DISubroutineType has a 'cc' field which should be a DW_CC_ enum. If
it is present and non-zero, the backend will emit it as a
DW_AT_calling_convention attribute. On the CodeView side, we translate
it to the appropriate enum for the LF_PROCEDURE record.

I added a new LLVM vendor specific enum to the list of DWARF calling
conventions. DWARF does not appear to attempt to standardize these, so I
assume it's OK to do this until we coordinate with GCC on how to emit
vectorcall convention functions.
