Peter Collingbourne 599cb8e430 Add support for language-specific address spaces. On top of that, 
add support for the OpenCL __private, __local, __constant and
__global address spaces, as well as the __read_only, _read_write and
__write_only image access specifiers.  Patch originally by ARM;
language-specific address space support by myself.

John McCall 2de87f67e5 Reorganize the emission of (unfoldable) constant casts a bit, and 
make sure that upcasts of member pointer types are covered as constants.
Fixed rdar://problem/9130221

Ken Dyck 1c80fd1346 Introduce a CharUnits FieldOffsetInChars variable in AppendField() to 
replace some uses of FieldOffsetInBytes. The remaining uses of
FieldOffsetInBytes will be replaced once NextFieldOffsetInBytes is converted
to CharUnits. No change in functionality intended.

John McCall 0217dfc2ba Perform zero-initialization of virtual base classes when emitting 
a zero constant for a complete class.  rdar://problem/8424975

To make this happen, track the field indexes for virtual bases
in the complete object.  I'm curious whether we might be better
off making CGRecordLayoutBuilder *much* more reliant on
ASTRecordLayout;  we're currently duplicating an awful lot of the ABI
layout logic.

builders unhappy.

Ken Dyck b0fcc59e19 Add a helper function, ASTContext::toBits(), that converts sizes in 
CharUnits to sizes in bits, and use it to tidy up the places where the
conversion was done explicitly.

John McCall f3a8860ee1 More capturing of 'this': implicit member expressions. Getting that 
right for anonymous struct/union members led to me discovering some
seemingly broken code in that area of Sema, which I fixed, partly by  
changing the representation of member pointer constants so that    
IndirectFieldDecls aren't expanded.  This led to assorted cleanups with   
member pointers in CodeGen, and while I was doing that I saw some random
other things to clean up.

Jay Foad 6d4db0c885 PR5207: Change APInt methods trunc(), sext(), zext(), sextOrTrunc() and 
zextOrTrunc(), and APSInt methods extend(), extOrTrunc() and new method
trunc(), to be const and to return a new value instead of modifying the
object in place.
