b31eebd3fd AsmPrinter: Get rid of llvm$workaround$fake$stub$ 
We currently emit labels with the prefix Lllvm$workaround$fake$stub$ if
the target's MCAsmInfo has getLinkOnceDirective() mapped to something
interesting.  This was apparently a work around introduced in r31033 for
binutils that we don't need anymore.

d7d43dc435 DebugInfo: Do not use the DWARF Version for the .debug_pubnames or .debug_pubtypes version field 
Summary:
LLVM would generate DWARF with version 3 in the .debug_pubname and
.debug_pubtypes version fields.  This would lead SGI dwarfdump to fail
parsing the DWARF with (in the instance of .debug_pubnames) would exit
with:
dwarfdump ERROR:  dwarf_get_globals: DW_DLE_PUBNAMES_VERSION_ERROR (123)

This fixes PR16950.

f04e4efcaa Turn on pubnames by default on linux. 
Until gdb supports the new accelerator tables we should add the
pubnames section so that gdb_index can be generated from gold
at link time. On darwin we already emit the accelerator tables
and so don't need to worry about pubnames.

0710bfa866 Add the start of DIE hashing for DWARF4 type units and split dwarf

Currently only hashes the name of CUs and the names of any children,
but it's an obvious first step to show the framework. The testcase
should continue to be correct, however, as it's an empty TU.

3dee575b8d Add preliminary support for hashing DIEs and breaking them into 
type units.

Initially this support is used in the computation of an ODR checker
for C++. For now we're attaching it to the DIE, but in the future
it will be attached to the type unit.

This also starts breaking out types into the separation for type
units, but without actually splitting the DIEs.

In preparation for hashing the DIEs this adds a DIEString type
that contains a StringRef with the string contained at the label.
