ac3f016599 DebugInfo: GDBIndexEntry*String conversion functions now return const char* for easy llvm::formating 
This was previously invoking UB by passing a user-defined type to
format. Thanks to Jordan Rose for pointing this out.

9599f51559 Unshift the GDB index/GNU pubnames constants modified in r191025 
Based on code review feedback from Eric Christopher, unshifting these
constants as they can appear in the gdb_index itself, shifted a further
24 bits. This means that keeping them preshifted is a bit inflexible, so
let's not do that.

Given the motivation, wrap up some nicer enums, more type safety, and
some utility functions.

Names open to bikeshedding. Could switch back to the constants being
unshifted, but this way seems a bit easier to work with.

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.

2460f32a8a Despite what the GCC wiki says, a quick search shows that 
DW_AT_GNU_template_name = 0x2110, not 0x2108. That would explain those 
attr #0x2110 under the DW_TAG_GNU_template_template_param I'm seeing. Migrate
from documented values to reality.
