Eric Christopher bfa4dc5512 Rename EmitStopPoint in CGDebugInfo to EmitLocation. "stop points" don't 
exist anymore.

Eric Christopher e655657c94 Call UpdateLineDirectiveRegion every time we want to emit a stop 
point in the code. Ensures that we don't miss any places and the
check is reasonably cheap.

Devang Patel e24d324762 Use new DIBuilder::finalize() at the end to wrap up debug info encoding for a translation unit.

Chris Lattner 01cf8db38b now that we have a centralized place to do so, add some using declarations for 
some common llvm types: stringref and smallvector.  This cleans up the codebase
quite a bit.

John McCall 147d021b75 Emit the structure layout of the block literal parameter to a block 
invocation function into the debug info.  Rather than faking up a class,
which is tricky because of the custom layout we do, we just emit a struct
directly from the layout information we've already got.

Also, don't emit an unnecessarily parameter alloca for this "variable".

Devang Patel 14524e0f24 If an aggregate argument is passed indirectly because it has non trivial 
destructor or copy constructor than let debug info know about it.

John McCall 351762cda2 A few more tweaks to the blocks AST representation: 
- BlockDeclRefExprs always store VarDecls
  - BDREs no longer store copy expressions
  - BlockDecls now store a list of captured variables, information about
    how they're captured, and a copy expression if necessary
    
With that in hand, change IR generation to use the captures data in       
blocks instead of walking the block independently.        

Additionally, optimize block layout by emitting fields in descending
alignment order, with a heuristic for filling in words when alignment
of the end of the block header is insufficient for the most aligned
field.

Devang Patel 91bbb5547d Introduce -flimit-debug-info. 
In this experimental mode try avoiding debug info emission for classes as much as possible. The goal is to reduce size of produced debuginfo without reducing quality of debug info in general. This is a work in progress.

Dan Gohman 196f71006e Introduce a new temporary MDNode concept. Temporary MDNodes are 
not part of the IR, are not uniqued, and may be safely RAUW'd.

Devang Patel 268ad093a7 Untangle filename/dirname confusion. Store constructed strings on the side. Avoid use of Path.makeAbsolute(). 
DW_TAG_compile_unit uses two attributes DW_AT_name and DW_AT_comp_dir. Their expected values are:

$ clang foo.c -g
  DW_AT_name - foo.c
  DW_AT_comp_dir - `pwd`

$ clang one/two/foo.c -g
  DW_AT_name - one/two/foo.c
  DW_AT_comp_dir - `pwd`

$ clang /tmp/one/foo.c -g
  DW_AT_name - /tmp/one/foo.c
  DW_AT_comp_dir - empty

Devang Patel 0884a60eb5 Keep track of artificial scopes introduced by line directives. For example, 
#line 41 "bar.c"
  dummy (1, i);
#line 24 "bar.h"
  i = f2 (i);
#line 44 "bar.c"

This is tested by step-line.exp in gdb testsuite.

John McCall 8b07ec253d Substantially alter the design of the Objective C type AST by introducing 
ObjCObjectType, which is basically just a pair of
  one of {primitive-id, primitive-Class, user-defined @class}
with
  a list of protocols.
An ObjCObjectPointerType is therefore just a pointer which always points to
one of these types (possibly sugared).  ObjCInterfaceType is now just a kind
of ObjCObjectType which happens to not carry any protocols.

Alter a rather large number of use sites to use ObjCObjectType instead of
ObjCInterfaceType.  Store an ObjCInterfaceType as a pointer on the decl rather
than hashing them in a FoldingSet.  Remove some number of methods that are no
longer used, at least after this patch.

By simplifying ObjCObjectPointerType, we are now able to easily remove and apply
pointers to Objective-C types, which is crucial for a certain kind of ObjC++
metaprogramming common in WebKit.

Devang Patel c5ffabc94f If given location is invalid then use current location.
