c25c908977 Add an option to pad an uleb128 to MCObjectWriter and remove the uleb128 encoding from the DWARF asm printer. 
As a side effect we now print dwarf ulebs with .ascii directives.

c3e48c38bf Dwarf: [PR11022] Fix emitting DW_AT_const_value(>i64), to be host-endian-neutral. 
Don't assume APInt::getRawData() would hold target-aware endianness nor host-compliant endianness. rawdata[0] holds most lower i64, even on big endian host.

FIXME: Add a testcase for big endian target.

FIXME: Ditto on CompileUnit::addConstantFPValue() ?

44d798d976 Add support for a new extension to the .file directive: 
.file filenumber "directory" "filename"

This removes one join+split of the directory+filename in MC internals. Because
bitcode files have independent fields for directory and filenames in debug info,
this patch may change the .o files written by existing .bc files.

6618a241f7 Add a new wrapper node for a DILexicalBlock that encapsulates it and a 
file. Since it should only be used when necessary propagate it through
the backend code generation and tweak testcases accordingly.

This helps with code like in clang's test/CodeGen/debug-info-line.c where
we have multiple #line directives within a single lexical block and want
to generate only a single block that contains each file change.

1dd4e56d55 Do not unnecessarily use AT_specification DIE because it does not add any value. 
Few weeks ago, llvm completely inverted the debug info graph. Earlier each debug info node used to keep track of its compile unit, now compile unit keeps track of important nodes. One impact of this change is that the global variable's do not have any context, which should be checked before deciding to use AT_specification DIE.

94c7ddb6f5 Until now all debug info MDNodes referred to a root MDNode, a compile unit. This simplified handling of these needs in dwarf writer. However, one side effect of this is that during link time optimization all these MDNodes are _not_ uniqued. In other words there will be N number of MDNodes describing "int", "char" and all other types, which would suddenly grow when each object file starts using libraries like STL. 
MDNodes graph structure such that compiler unit keeps track of important MDNodes and update dwarf writer to process mdnodes top-down instead of bottom up.
