ae56eecf5f Add support for a temporary forward decl type. We want this so we 
can rauw forward declarations if we decide to emit the full type.

conventions. Also, clarify the grouping of one of the asserts to silence
-Wparentheses.

6647b83087 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.

59e27c5f12 Do not use named md nodes to track variables that are completely optimized. This does not scale while doing LTO with debug info. New approach is to include list of variables in the subprogram info directly.

eb1bb4e419 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.

b5ea255fb4 Fix an off by one error while accessing complex address element of a DIVariable. 
This worked untill now because stars are aligned (i.e. num of complex address elments are always 0 or 2+ and when it is 2+ at least two elements are access together)

40eee1e970 Today, the language front ends produces llvm.dbg.* intrinsics, used to encode arguments' debug info, in order any way, most of the times. However, if a front end mix-n-matches llvm.dbg.declare and llvm.dbg.value intrinsics to encode debug info for arguments then code generator needs a way to find argument order. 
Use 8 bits from line number field to keep track of argument ordering while encoding debug info for an argument. That leaves 24 bit for line no, DebugLoc also allocates 24 bit for line numbers. If a function has more than 255 arguments then rest of the arguments will be ordered by llvm.dbg.* intrinsics' ordering in IR.

57c5a20364 Introduce DIBuilder. It is intended to be a front-end friendly interface to emit debuggging information entries in LLVM IR. 
To create debugging information for a pointer, using DIBUilder front-end just needs
	DBuilder.CreatePointerType(Ty, Size);
instead of
	DebugFactory.CreateDerivedType(llvm::dwarf::DW_TAG_pointer_type,
                                       TheCU, "", getOrCreateMainFile(),
                                       0, Size, 0, 0, 0, OCTy);
